Question

Name the following compound: CH3 – CH2 – CH2 – CH2 – CH3 Pentane Pentene Pentyne pentyl

Answer 1

This is pentane. The pent- from given that there are 5 carbons in a row, and the -ane from the fact they are all single bonds, thus pentane.

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

It is known that a hydrocarbon with general formula
`C_(n)H_(2n+2)` is known as an alkane. All atoms of an alkane are bonded by a single bond.

For example, the given compound is
`CH_(3)CH_(2)CH_(2)CH_(2)CH_(3)`. 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
`C_(n)H_(2n)` and contains a double bond is known as an alkene.

A hydrocarbon that has general formula
`C_(n)H_(2n-2)` and contains a triple bond is known as an alkyne.

Thus, we can conclude that name of the given compound is pentane.
