Question

What is the name of this hydrocarbon?

Answer 1

Answer:

C. 2-methylpropane

Explanation:

There are rules guiding the naming of hydrocarbons. Some of the rules are:

1.) The longest continuous chain is the parent chain:

The longest chain here is made up of 3-carbon atoms which is a propane compound

2.)The carbon atoms are numbered in the parent chain to indicate where branching or substitution takes place.

Here, it is in the second carbon atom in propane.

The branched group is methyl- which is a methane molecule that has lost a hydrogen atom.

This makes ths name of the compound to be:

2-methylpropane
