Which of the following statements is not true? A) The sp³C−H bond of an alkane is weaker than the spC−H bond of an alkyne. B) The carbon-carbon triple bond of an alkyne is shorter than the carbon-carbon bond of alkenes. C) The carbon-carbon triple bond of an alkene is exactly three times as strong as a carbon-carbon single bond of an alkane. D) The sp³C−H bond of an alkane is longer than the spC−H bond of an alkyne.

Question

Quizplus · Accepted Answer

The statement that the carbon-carbon triple bond of an alkene is exactly three times as strong as a carbon-carbon single bond of an alkane (C) is not true because alkenes do not have triple bonds; alkynes do. Additionally, the strength of a bond does not scale linearly with the number of bonds between atoms.
