alleryWhich multiple bond is present in an alkyne?
ACarbon-carbon single bond only
BCarbon-oxygen triple bond
CCarbon-carbon triple bond
DCarbon-carbon double bond
Answer & Solution
Correct answer: C. Carbon-carbon triple bond
1. The suffix -yne identifies an alkyne. Its characteristic multiple bond joins two carbon atoms.
2. That bond is a carbon-carbon triple bond, written C≡C. A carbon-carbon double bond, C=C, instead identifies an alkene.
3. Therefore option C is correct. A carbon-oxygen triple bond does not match the hydrocarbon bond asked for, and single bonds alone do not identify an alkyne.
