Question

Which of the following is general formula of Alkenyne:-

• A. $C_n{H}_{2n-2}$
  $n=4,5,\mathrm{6......}$
• B. $C_n{H}_{2n-4}$
  $n=4,5,\mathrm{6......}$
• C. $C_n{H}_{2n-4}$
  $n=2,3,\mathrm{4......}$
• D. $C_n{H}_{2n-2}$
  $n=2,\mathrm{3......}$

Answer 1

The correct option is A $C_n{H}_{2n-2}$

$n=4,5,\mathrm{6......}$

Alkenyne is an acyclic hydrocarbon with one $C-C$ double bond and one $C-C$ triple bond.

E.g. $C{H}_2=CH-C{H}_2-C\equiv C-C{H}_3$

General formula: $C_n{H}_{2n-4},n=4,5,\mathrm{6......}$
