Question

Hybridization of $1$ and $2$ carbon atom in $C{H}_2=C=C{H}_2$ are:

• A. $sp,sp$
• B. $s{p}^2,s{p}^2$
• C. $s{p}^2,sp$
• D. $s{p}^3,s{p}^2$

Answer 1

Answer: (C)

In this compound carbon atoms have following hybridization:
$\stackrel{1}{C}{H}_2=\stackrel{2}{C}=C{H}_2$
$s{p}^{2}sp$ Carbon one contains one $\pi$ bond and carbon two contains two $n$ bonds and hence, show $s{p}^2$ and $sp$ hybridization respectively.
