Edith Cooley · Answer 1

The name of given molecule is 3-Methylpent-2-ene.

Explanation:

First of all a carbon chain of five carbons was drawn. Then a double bond was made between carbon 3 and 4 (starting from left). A methyl group was drawn at middle carbon which is at position 3.

Molecule sketched was named as,

1) A longest chain containing double bond was selected and numbering was started from the end closest to double bond. Hence,

2-Pentene or Pent-2-ene

2) The position of substituent was specified before the parent name, Hence,

3-Methyl-2-Pentene or 3-Methylpent-2-ene
