Answer:
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
