Question

Which of the following species (A), (B), (C) and (D) has $s{p}^2$ hybridized carbon?
$CH{{}_3}^{+}$, $CH{{}_3}^{-}$, $\stackrel{\bullet }{C}H{}_3$, :$C{H}_2$

• A. A only
• B. A and B only
• C. A and C only
• D. A, C and D

Answer 1

Answer: (D)

A, C and D

$CH{{}_3}^{+}$, $\stackrel{\bullet }{C}H{}_3$, :$C{H}_2$ have $s{p}^2$ hybridized carbon because in $CH{{}_3}^{+}$, $\stackrel{\bullet }{C}H{}_3$, $3$ bond pair and zero lone pair and in :$C{H}_2$, $2$ bond pair and $1$ lone pair.
$CH{{}_3}^{-}$ has $s{p}^3$ hybridized carbon.
