Question

What are the hybridization states of each carbon atom(s) in the following molecules ?

(i) $C{H}_3\stackrel{\ast }{C}{H}_{2}C{H}_{2}C{H}_3$

(ii) $C{H}_2=C^{\ast }H-CH=C{H}_2$

(iii) $C{H}_3\stackrel{\ast }{C}H=CH-C{H}_3$

(iv) $H-\stackrel{\ast }{C}\equiv C-H$

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

Answer 1

The correct option is B $s{p}^3,s{p}^2,s{p}^2,sp$

Hybridization of carbon in any organic molecule can be easily determined.
Carbon with single bond has ${sp}^3$, carbon with double bond has ${sp}^2$ hybridization, and carbon with triple bond has $sp$ hybridization.
