alkene and alkyne

Alkenes are named after the parent alkane by replacing '-ane' of the alkane by '-ene'. Alkynes are named after the parent alkane by replacing the suffix '-ane' of the alkane by '-yne'. Thus, Suffix for alkenes: -ene Suffix for alkynes: -..

Alkanes Alkenes Alkynes General formula CH n H 2n+2 CH n H 2n CH n H 2n-2 Naming All the members end with 'ane' All the members end with 'ene’ All the members end with 'yne’ Physical state Members having 1-4 carbon atoms ..

Alkenes can be easily obtained by hydrogenation of alkynes. An alkyne on controlled hydrogenation with hydrogen in the presence of Ni or Pd at 200C give corresponding alkene. C n H 2 n - 2 + H 2 ..

Alkynes - Alkynes are unsaturated hydrocarbons with the general formula C n H 2 n - 2 . They are the most reactive as compared to alkenes and alkane..

In the IUPAC nomenculature, alkenes end with '-yne'. Condensed Formula Word root Primary Suffix IUPAC name and formula CH ≡ CH Eth - - yne Ethyne C 2 H 2 CH 3 - C ≡ CH Prop - - yne Propyne C 3 H 4 CH 3 - CH 2 - C ≡ CH But - - yne Butyne..

There are only a few methods available for the preparation of alkynes, in contrast to alkanes and alkenes. These are given bel..

Hydrogen atoms in ethyne and 1-alkynes, linked to the carbon atom having a triple bond on it, are acidic in nature. For example, ethyne (acetylene) is a weak acid: weaker than water but stronger than ammonia. This may be explained as follows: The -electrons are more weakly bound than ele..

Carbon-carbon triple bond, C=C, is a combination of one and two bonds. Alkynes give electrophilic addition reactions as they show reactivity due to the presence of bonds. This property is similar to alkenes but alkynes are less reactive than alkenes towards ..
