Question

The compound buta-1,2-diene has

• A. only $sp$ hybridised carbon atoms
• B. only $s{p}^2$ hybridised carbon atoms
• C. both $sp$ and $s{p}^2$ hybridised carbon atoms
• D. $sp,s{p}^2$ and $s{p}^3$ hybridised carbon atoms

Answer 1

The correct option is D $sp,s{p}^2$ and $s{p}^3$ hybridised carbon atoms


Carbon bonded with double bond on both the side is $sp$ hybridised. Carbon bonded with a double bond is $s{p}^2$ hybridised. Hence, buta-1,2-diene has $sp,s{p}^2$ and $s{p}^3$ hybridised carbon atoms. Therefore, the correct answer is option (d).
