Question

The hybridization of $N,C$ and $O$ shown in the following compound respectively, are:
$R-N=C=O$

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

Answer 1

The correct option is A $s{p}^2,sp,s{p}^2$

$R-\stackrel{..}{N}=C=\underset{..}{\stackrel{..}{O}}$
Only $\sigma$ bond is considered in predicting hybridization.
$N=2b.p+1l.p=3=s{p}^{2}C=2b.p=2=spO=1b.p+2l.p=3=s{p}^2$
