Question

The hybridization of carbons labelled 3, 4 and 5 in

$H{C}^1-C^2-C^{3}H=C^4=C^{5}H-C^{6}H=C^7{H}_2$ are?

• A. $S{P}^2$ only
• B. $S{p}^2$ in C-4 and $S{P}^3$ in 3 and 5
• C. $S{p}^2$ in C-3 and C-5 and $SP$ in C-4
• D. $SP$ only

Answer 1

The correct option is C

$S{p}^2$ in C-3 and C-5 and $SP$ in C-4

Carbon which has $3\sigma$ bonds and $1\pi$ bond in C-3 and C-5 $s{p}^2$ hybridised.

Carbon which has $3\sigma$ bonds and $1\pi$ bond as in C-4 is sp hybridised.
