Question

Hybridization on carbon in carbonion $\stackrel{⊝}{C}{H}_3$ is:

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

Answer 1

The correct option is A $s{p}^3$

Carbon atom electronic configuration is $\left[He\right]2s^{1}2p^3$.

$\stackrel{⊝}{C}$ ion electronic configuration is $\left[He\right]2s^{2}2p^3$.

$\stackrel{⊝}{C}$ ion undergoes $s{p}^3$ hybridization and combines with three hydrogen atoms to form $\stackrel{⊝}{C}{H}_3$ ion.

So hybridization of carbon in carbonion $\stackrel{⊝}{C}{H}_3$ is $s{p}^3$ hybridization.

So answer is A.
