Question

Which among the following compounds has both $s{p}^2$ and $s{p}^3$ hybridizations?

• A. Propene
• B. Propyne
• C. Propane
• D. Allene (Propa-1,2-diene)

Answer 1

The correct option is A Propene

a) $\underset{s{p}^2}{C{H}_2}=\underset{s{p}^2}{CH}-\underset{s{p}^3}{C{H}_3}$
Propene has both $s{p}^2$ and $s{p}^3$ hybridized carbons.

b) $\underset{sp}{CH}\equiv \underset{sp}{CH}-\underset{s{p}^3}{C{H}_3}$
Propyne has $sp$ and $s{p}^3$ hybridized carbons.

c) $\underset{s{p}^3}{C{H}_3}-\underset{s{p}^3}{C{H}_2}-\underset{s{p}^3}{C{H}_3}$
Propane has only $s{p}^3$ hybridized carbons,

d) $\underset{s{p}^2}{C{H}_2}=\underset{sp}{C}=\underset{s{p}^2}{C{H}_2}$
Allene (Propa-1,2-diene) has only $sp$ and $s{p}^2$ hybridized carbons.
