Question

An alkene with molecular formula C8H16 on oxidation with hot KMnO4 gives acetone and 3-pentanone.The structure of the alkene is

Answer 1

Answer:

Explanation:

3-ethyl-2-methyl-Pent-2-ene

Answer 2

The alkene which comes with molecular formula $C_{8}H_{16}$ on oxidation with hot $KMnO_4$  gives acetone and 3-pentanone is -  3-ethyl-2-methyl-Pent-2-ene.

• If we see the structure of acetone and 3-pentanone the solution will be clear to us. We can say that on the oxidation of an alkene which's of  $C_{8}H_{16}$  molecular formula, this will break into two parts and the oxygen molecules will be added with them. And can make acetone and 3-pentanone.
• The molecular formula of acetone is, $C_3H_6O$. And the molecular formula of 3-pentanone is $C_5H_{10}O$.
• The structure of the alkene, acetone, and 3-pentanone be -
