Answer :
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: Option (4) is the correct answer.
Explanation:
A hydrocarbon in which all atoms are bonded by single bond and have a general formula [tex]C_{n}H_{2n+2}[/tex] 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 [tex]C_{n}H_{2n}[/tex] 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 [tex]C_{n}H_{2n-2}[/tex] 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.
