Which of the following molecules represents the order of hybridization sp2,sp2,sp,sp{sp}^{2}, {sp}^{2}, sp, sp from left to right atoms?

Options

  1. ACH2=CH−CH=CH2{CH}_{2} = CH - CH = {CH}_{2}
  2. BCH2=CH−C≡CH{CH}_{2} = CH - C ≡ CH
  3. CHC≡C−C≡CHHC ≡ C - C ≡ CH
  4. DCH3−CH=CH−CH3{CH}_{3} - CH = CH - {CH}_{3}

Correct answer

B. CH2=CH−C≡CH{CH}_{2} = CH - C ≡ CH

Step-by-step solution

Hybridization can be calculated by: Total number of sigma bond + Total number of lone pair.

CH2sp2=CHsp2−Csp≡CHsp\overset{{sp}^{2}}{{CH}_{2}} = \overset{{sp}^{2}}{CH} - \overset{sp}{C} ≡ \overset{sp}{CH}
