When 2-methyl-but-2-ene undergoes hydrolysis, it forms 2- methylbutan-2-ol (X). When 2 -methyl-but- 2 -ene undergoes ozonolysis and further reacts with Zn−H2O, the products such as propan- 2 -one ( Y )and acetaldehyde (Z) are formed. The products X,Y and Z formed are shown below.
Therefore , X is (H3C)2C(OH)CH2CH3 Y is (CH3)2CO Z is CH3CHO
