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 h..

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 alkanes..

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..

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..

These alkanes also have special common names when both the halogen atoms are attached to the same C-atom. These are called 'gem-dihalides', or are also called alkylidene dihalides or simply, alkylidene halides. ..

Alkynes can be prepared from di- and tetra- halogen derivatives of alkanes..

Alkenes are more reactive than alkanes due to the presence of a double bond. The carbon-carbon double bond consists of a strong bond and a weak p bond. The typical reactions of alkenes involve the breaking of this weaker p bond, viz., and formation of two sigma ( ..
