Which of the following compounds has sp3 orbital with 1/4 (25%) s-character and 75% p-character?

1. CH3-CH=CH-CH2
2. CH3-C≡C-CH3
3. CH3-CH=CH-C=CH2
4. CH3-CH2-CH=CH-CH3

Correct answer: CH3-CH2-CH=CH-CH3

Solution

In sp3 hybridization, the orbital has 25% s-character and 75% p-character. Only CH3-CH2-CH=CH-CH3 contains sp3-hybridized carbon atoms in the CH3 and CH2 groups.
