Question

Which statement about the carbon–carbon triple bond is FALSE?
Options
A It is shorter than a C=C bond
B It consists of one σ and two π bonds
C Free rotation is possible around the triple bond
Correct Answer
D The carbons are sp hybridized
Correct Answer

Option C is the correct answer.

Detailed Explanation

Free rotation is not possible around a triple bond because the two π bonds would have to break (though the linear geometry makes rotation irrelevant).

Hint

π bonds prevent free rotation.
