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 ..

When the hydrogen to carbon ratio is less than that required for alkanes in hydrocarbons, they are called as unsaturated hydrocarbons. The valencies of carbon atoms in these compounds are satisfied by the formation of a double (=) triple ( ) bonds. Compounds containing a double bond are called ..

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 (earlier called acetylenes), are those unsaturated hydrocarbons containing a carbon-carbon triple bond (-C C-). A general formula C n H 2 n - 2 , can represent alkynes. Alkynes posses four hydrogen atoms less than the alkane and two hydrogen atoms less..

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..

Laboratory Preparation of Alkynes - 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..
