Which answer provides the correct name for the following hydrocarbon?

Moving left to right: A hydrocarbon chain made of a methyl group (CH subscript three) single bond methylene (CH subscript two) single bond methylene (CH subscript two) single bond CH subscript two single bond methyl group (CH subscript three) .

It looks like:  CH3 - CH2 - CH2 - CH2 - CH3

pentene
pentane
2-pentane
pentyne

Respuesta :

1) Hydrocarbon: CH3 - CH2 - CH2 - CH2 - CH3

2) Only single bonds => alkane => sufix ane

3) no substitutions

4) 5 carbons = > prefix penta.

Therefore, the name is pentane.

Answer: Option (b) is the correct answer.

Explanation:

In the given molecule, there are five carbon atoms attached linearly to each other will single bonds only.

So, it is known that when a compound contains only carbon and hydrogen atoms attached  single bondedly to each other then this type of hydrocarbon is known as alkane.

Their general formula is [tex]C_{n}H_{2n+2}[/tex], where n is the number of carbon atoms present. Suffine "ane" is added to the name of alkane.

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