Question

Which one of the underlined carbons is $s{p}^3$-hybridized?

• A. $C{H}_3\underset{–}{C}H=C{H}_2$
• B. $C{H}_3\underset{–}{C}{H}_{2}N{H}_2$
• C. $C{H}_3\underset{–}{C}ON{H}_2$
• D. $C{H}_{3}C{H}_2\underset{–}{C}N$

Answer 1

The correct option is B $C{H}_3\underset{–}{C}{H}_{2}N{H}_2$

A- $s{p}^2$ hybridization

B-$s{p}^3$ hybridization

C-$s{p}^2$ hybridization

D-$sp$ hybridization
Option B is correct.
