Answer: Option (a) is the correct answer.
Explanation:
It is known that a hydrocarbon with general formula [tex]C_{n}H_{2n+2}[/tex] is known as an alkane. All atoms of an alkane are bonded by a single bond.
For example, the given compound is [tex]CH_{3}CH_{2}CH_{2}CH_{2}CH_{3}[/tex]. There are five carbon atoms and 12 hydrogen atoms.
So, it is an alkane whose name is pentane.
Whereas a hydrocarbon that has general formula [tex]C_{n}H_{2n}[/tex] and contains a double bond is known as an alkene.
A hydrocarbon that has general formula [tex]C_{n}H_{2n-2}[/tex] and contains a triple bond is known as an alkyne.
Thus, we can conclude that name of the given compound is pentane.
