Question

Give the name of the following molecule. EXTRA POINTS PLEASE HELP

A compound with a total of six carbons with a double bond and the rest single bonds. There is a chain of five carbons across the bottom with a double bond between the third and fourth carbons when counting form left to right. There in a methyl group branching off of the middle carbon.

Answer 1

The molecule with six carbons, a double bond between the third and fourth carbons, and a methyl group on the middle carbon is named 3-methyl-2-pentene, according to IUPAC nomenclature rules.

Step-by-step explanation:

The name of the molecule described with a total of six carbons, a double bond between the third and fourth carbons, and a methyl group on the middle carbon is 3-methyl-2-pentene.

This name is derived by following the IUPAC nomenclature rules:

The longest chain containing the double bond has five carbon atoms, so the parent compound is a pentene.

The double bond should have the lowest possible numbers, and numbering from the left gives us the double bond starting at the second carbon, thus making it a 2-pentene.

Since there is a methyl group on the middle carbon, which is the third carbon in this case, it is named as 3-methyl.

Answer 2

There isn t a 'middle' carbon because there is an even number of them

If the methyl group braches off the 3rd carbon the name is

hexa-3-methyl-3-ene
