Oxidation of primary alcohols. OH- will attack more positively charged carbon. Undergo self condensation to produce b-keto esters. This reaction is Claisen Condensation. An Ylide is a neutral molecule having a negative carbon adjacent to a positive hetero atom. Phosphorus ylides are also called phosphoranes. Reagents are either per acetic acid or perbenzoic acid or pertrifluoroacetic acid or permonosulphuric acid.

The classes of organic compounds containing carbonyl group CO as the functional group are aldehydes, ketones, carboxylic acids and their derivates. These are collectively called carbonyl compounds. Nature of carbonyl group: Oxygen atom in carbonyl group is far more electronegative than carbon atom. Hence carbonyl carbon acquires positive charge and carbonyl oxygen carries negative charge. Thus, the carbonyl group is polar in nature. Methods of preparation of Aldehydes and Ketones: a By controlled oxidation of primary and secondary alcohol, aldehydes and ketones are produced. Preparation of Aldehydes: a Acyl chloride acid chloride is hydrogenated using, palladium on barium sulphate which is partially poisoned by the addition of S or quinoline.

Another class of organic molecules contains a carbon atom connected to an oxygen atom by a double bond, commonly called a carbonyl group. The trigonal planar carbon in the carbonyl group can attach to two other substituents leading to several subfamilies aldehydes, ketones, carboxylic acids and esters described in this section. Both aldehydes and ketones contain a carbonyl group , a functional group with a carbon-oxygen double bond. The names for aldehyde and ketone compounds are derived using similar nomenclature rules as for alkanes and alcohols, and include the class-identifying suffixes -al and -one , respectively. In an aldehyde, the carbonyl group is bonded to at least one hydrogen atom. In a ketone, the carbonyl group is bonded to two carbon atoms. In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibits sp 2 hybridization.

На лице Сьюзан на мгновение мелькнуло недоумение. Она побледнела и прошептала: - О Боже… Стратмор утвердительно кивнул, зная, что она догадалась. - Он целый год хвастался, что разрабатывает алгоритм, непробиваемый для грубой силы. - Н-но… - Сьюзан запнулась, но тут же продолжила: - Я была уверена, что он блефует.

Хейл подошел к буфету, с грохотом открыл решетчатую дверцу, достал из холодильника пластиковую упаковку тофу, соевого творога, и сунул в рот несколько кусочков белой студенистой массы. Затем облокотился о плиту, поправил широкие серые брюки и крахмальную рубашку. - И долго ты собираешься здесь сидеть.

 - Это очень важно. Клушар заморгал. - Я не знаю… эта женщина… он называл ее… - Он прикрыл глаза и застонал. - Как.

И в тот же миг ей открылась ужасающая правда: Грег Хейл вовсе не заперт внизу - он здесь, в Третьем узле. Он успел выскользнуть до того, как Стратмор захлопнул крышку люка, и ему хватило сил самому открыть двери. Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась.

Это была цифровая мультимедийная трансляция - всего пять кадров в секунду. На экране появились двое мужчин: один бледный, коротко стриженный, другой - светловолосый, с типично американской внешностью. Они сидели перед камерой наподобие телеведущих, ожидающих момента выхода в эфир.

 - Дэвид. В этот момент в нескольких метрах под помещением шифровалки Стратмор сошел с лестницы на площадку. Сегодняшний день стал для него днем сплошных фиаско. То, что началось как в высшей степени патриотическая миссия, самым неожиданным образом вышло из-под контроля.

Снова открыв окно, Сьюзан изучила содержащуюся в нем информацию. Какая-то бессмыслица. Вначале был зарегистрирован нормальный ввод замка, в тот момент, когда она выходила из помещения Третьего узла, однако время следующей команды отпирания показалось Сьюзан странным.
