22.2: Alkanes, Cycloalkanes, Alkenes, Alkynes, and Aromatics

The largest database 1 of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. The number of potential organic compounds has been estimated 2 at 10 60 —an astronomically high number. The existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. The simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. Even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. In addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. Many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory.

Halogens, especially chlorine and bromine add on alkenes readily producing a dihalogen derivatives. Since there is very little difference between the electronegativities of carbon and hydrogen, alkanes are almost non-polar.

To compare the chemical reactivity of an alkane, an alkene, and an aromatic compound. The carbon 11F Section s First 4 members are gases.

Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups. Alkanes are identified because the carbon chain has only single bonds. Common alkanes include methane natural gas , propane heating and cooking fuel , butane lighter fluid and octane automobile fuel. Alkenes have at least one double bond and alkynes have at least one triple bond. The most common alkyne is ethyne, better known as acetylene. Alkenes have the formula C n H 2n and alkynes use the formula C n H 2n

The physical properties of alkenes and alkynes are generally similar to those of alkanes or cycloalkanes with equal numbers of carbon atoms. Alkenes react with a much richer variety of compounds than alkanes. The characteristic reaction of alkanes is substitution ; that of alkenes and alkynes is addition to the double or triple bond. Hydrogenation is the addition of molecular hydrogen H 2 to a multiple bond, which converts alkenes to alkanes. The reaction occurs at a convenient rate only in the presence of certain finely divided metal catalysts , such as nickel Ni , platinum Pt , palladium Pd , or rhodium Rh. Hydrogenation is used to prepare alkanes and cycloalkanes and also to change the physical properties of highly unsaturated vegetable oils to increase their shelf life.

Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups. The simplest organic compounds are the alkanes.

Alkanes are very versatile and are being used as solvents, heating oils, fuels, in fat synthesis , in the synthesis of fatty acids by air oxidation, in the manufacture of albumen, in the transformation to olefins, etc. The latter are starting materials for the preparation of alkyl benzenes which play an important role in the synthesis of degradable detergents. The largest amount of methane produced is used for heating purposes. Only a small part is further processed to yield, for example, hydrogen cyanide, acetylene, chloroalkanes, carbon disulfide, and carbon black. The mixture known as syngas is being used in the synthesis of methanol , for the preparation of aldehydes and alcohols by oxosynthesis hydroformylation and for the generation of hydrogen, e. Methane is an important raw material for large-scale industrial syntheses, for example, in the syntheses of halogenated hydrocarbons, such as methyl chloride, methylene chloride, chloroform, carbontetrachloride, etc.


Alkanes, Alkenes, and Alkynes. Unbranched alkenes are analogous to unbranched alkanes. Each C uses its three sp2 atomic orbitals to form the two C-H.


Physical properties

The Reactions of Alkanes, Alkenes, and Alkynes. In the absence of a spark or a high-intensity light source, alkanes are generally inert to chemical reactions. However, anyone who has used a match to light a gas burner, or dropped a match onto charcoal coated with lighter fluid, should recognize that alkanes burst into flame in the presence of a spark.

Одним глазом он следил за тенью, другим - за ступенями под ногами. Вдруг Халохоту показалось, что тень Беккера как бы споткнулась. Она совершила судорожный рывок влево и вроде бы закружилась в воздухе, а затем снова прильнула к центру лестницы. Халохот сделал стремительный прыжок.

Он был настолько погружен в свои мысли, что не заметил человека в очках в тонкой металлической оправе, который следил за ним с другой стороны улицы. ГЛАВА 18 Стоя у громадного окна во всю стену своего кабинета в токийском небоскребе, Нуматака с наслаждением дымил сигарой и улыбался. Он не мог поверить в свою необыкновенную удачу. Он снова говорил с этим американцем, и если все прошло, как было задумано, то Танкадо сейчас уже нет в живых, а ключ, который он носил с собой, изъят. В том, что он, Нуматака, в конце концов решил приобрести ключ Энсея Танкадо, крылась определенная ирония.

Alkanes, Alkenes, and Acetylenes

Их синеватое свечение придавало находящимся предметам какую-то призрачную расплывчатость. Она повернулась к Стратмору, оставшемуся за дверью. В этом освещении его лицо казалось мертвенно-бледным, безжизненным. - Сьюзан, - сказал.  - Дай мне двадцать минут, чтобы уничтожить файлы лаборатории систем безопасности. После этого я сразу перейду к своему терминалу и выключу ТРАНСТЕКСТ. - Давайте скорее, - сказала Сьюзан, пытаясь что-нибудь разглядеть сквозь тяжелую стеклянную дверь.

Расстрельная камера, мысленно усмехнулся. Халохот оценил расстояние до входа. Семь ступеней.

Цифровая крепость оказалась фарсом, наживкой для Агентства национальной безопасности. Когда Стратмор предпринимал какой-либо шаг, Танкадо стоял за сценой, дергая за веревочки. - Я обошел программу Сквозь строй, - простонал коммандер. - Но вы же не знали. Стратмор стукнул кулаком по столу.

 - Почему вы считаете, будто Танкадо не знал, что на него совершено покушение. Смит откашлялся. - Халохот ликвидировал его с помощью НТП - непроникающей травматической пули. Это резиновая капсула, которая при попадании растворяется.

Все застыли в ужасе. На экране перед ними высветилось сообщение об ошибке: НЕДОПУСТИМЫЙ ВВОД. ТОЛЬКО В ЦИФРОВОЙ ФОРМЕ - Черт его дери! - взорвался Джабба.  - Только цифровой.

ГЛАВА 45 Дэвид Беккер бесцельно брел по авенида дель Сид, тщетно пытаясь собраться с мыслями. На брусчатке под ногами мелькали смутные тени, водка еще не выветрилась из головы.
