Question

The compound 1,2-butadiene has

• A. only sp hybridized carbon atoms
• B. only $sp^2$ hybridized carbon atoms
• C. both sp and $sp^2$ hybridized carbon atoms
• D. sp, $sp^2$and $sp^3$ hybridized carbon atoms

Answer 1

Answer: (D)

sp, $sp^2$and $sp^3$ hybridized carbon atoms

Answer 2

The structure of 1, 2 butadiene is $H_2C = C = CHCH_3$ $C_1$ is $sp^2, C_2$ is $sp, C_3$ is $sp^2$ and $C_4$ is $sp^3$ hybridised.
