Which of the following compounds contain all the carbon atoms in the same hybridisation state
Options
- AH - C ≡ C - C ≡ C - H
- BCH 3 - C ≡ C - CH 3
- CCH 2 = C = CH 2
- DCH 2 = CH - C ≡ CH
Correct answer
A. H - C ≡ C - C ≡ C - H
Step-by-step solution
Key idea pi -bond do not participate in hybridisation In H−C≡C−C=−H all carbon atoms are in same hybridization state i.e., sp hybridized. a. H - C sp ≡ C sp - C sp ≡ C sp - H b. CH 3 sp 3 - C sp ≡ C sp - CH 3 sp 3 c. CH 2 sp 2 = C sp = CH 2 sp 2 d. CH 2 sp 2 = CH - sp 2 C sp ≡ CH sp
