Question

The general formula for the alkyne series is: CnH2n+2 CnH2n CnH2n-2 CnHn+2

Answer 1

The general  formula  for  alkyne  series  is     CnH2n-2

 This is because alkyne  is unsaturated  hydrocarbon   which has  one  triple  bond   and   has  no functional  group  from   homologous series. Alkyne  has  a  general formula of  CnH2n-2

An  example  of an  alkyne  in  ethyne    with HC≡CH  chemical formula ,

another example is propyne   with  CH3C≡CH  formula
