Question

Methods of preparation of
a ) Alkanes
b ) Alkenes &
c ) Alkynes

Answer 1

A) Alkanes :- 1)Decarboxylation ,
2)Wurtz Reaction,
3)By reduction of alkyl halides,
4)By reduction of carbonyl compounds.
B)Alkenes:-1) alkenes have double bond between carbon compounds. General formula is CnH2n.
2) alkenes are obtained by heating alkyl halides with alcoholic potash.
C) Alkynes :-1) alkyl substitution in Acetylene
2)Dehyrohalogenation of vic- Dihalides or gem -Dihalides .
