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?

Options:

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

S P

in C-4

D .

S P

only

Answer: Option C
:
C

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

Carbon which has $3 σ$ bonds and $1 π$ bond as in C-4 is sp hybridised.
