How many $σ$ - and $π$ -bonds are present in each of the following molecules?
(a) $H C \equiv C - C H = C H - C H_{3}$
(b ) $C H_{2} = C = C H - C H_{3}$

Open in App

Solution

(a) $H C \equiv C - C H = C H - C H_{3}$

Total pi bond $= 3 π$

Total sigma bond $= 4 (C - C) + 6 (C - H) = 10 σ$

(b ) $C H_{2} = C = C H - C H_{3}$

Total pi bond $= 2 π$

Total sigma bond $= 3 (C - C) + 6 (C - H) = 9 σ$
