Question

A carbon-carbon triple bond is found in a molecule of

Answer 1

The answer is (4) butyne. The carbon-carbon triple bond is found in alkynes. And the alkynes has -yne at the end of the name. "-ene" end means that it is alkene and has carbon-carbon double bonds.

Answer 2

Answer: Option (4) is the correct answer.

Explanation:

A hydrocarbon in which all atoms are bonded by single bond and have a general formula $C_{n}H_{2n+2}$ is known as an alkane.

A suffix "ane" adds at the end of the name of this hydrocarbon.

A hydrocarbon in which an  atom is bonded by a double bond and have a general formula $C_{n}H_{2n}$ is known as an alkene.

A suffix "ene" adds at the end of the name of this hydrocarbon.

A hydrocarbon in which an atom is bonded by triple bond and have a general formula $C_{n}H_{2n-2}$ is known as an alkene.

A suffix "yne" adds at the end of the name of this hydrocarbon.

Thus, we can conclude that a carbon-carbon triple bond is found in a molecule of butyne.
