`A or B overset((i)O_3)underset((ii)Zn//H_2O)toCH_3CHO`. A and B are the two geometrical isomers. Identify them.

Text Solution

Verified by Experts

The alkene which given only acetaldehyde on ozonolysis is 2-butene `(CH_(3)CH = CHCH_(3))`.
`CH_(3)CH = O + O = CHCH_(3) rArr CH_(3)CH = CHCH_(3)`
So, A and B are the two geometrical isomers of 2-butene:
