Question

Which of the following organic compounds has same hybridization as its combustion product, $C{O}_2$?

• A. Ethane
• B. Ethyne
• C. Ethene
• D. Ethanol

Answer 1

Answer: (B)

Ethyne

The structure of $C{O}_2$ is as follows :

$O=C=O$

Here, carbon is $sp$ hybridised.

The structure of ethyne is as follows :

$CH\equiv CH$

Here also, both carbon atoms are $sp$ hybridised.

Therefore, the correct option is B.
