Problem 10 : Draw the structural formula of the major product formed when propene undergoes the following reactions:
(a) With HBr in the absence of peroxide (b) With Cl₂ in the presence of sunlight (c) With H₂SO₄ in the presence of HgSO₄ (d) With KMnO₄ in acidic medium
Solution :
(a) With HBr in the absence of peroxide: [ \text{CH}_2 = \text{CH}_2 + \text{HBr} \rightarrow \text{CH}_3 - \text{CH}_2 - \text{Br} ]
(b) With Cl₂ in the presence of sunlight: [ \text{CH}_2 = \text{CH}_2 + \text{Cl}_2 \rightarrow \text{CH}_2\text{ClCH}_2 ]
(c) With H₂SO₄ in the presence of HgSO₄: [ \text{CH}_2 = \text{CH}_2 + \text{H₂SO₄} \rightarrow \text{CH}_3\text{CHO} ]
(d) With KMnO₄ in acidic medium: [ \text{CH}_2 = \text{CH}_2 + \text{KMnO}_4 \rightarrow \text{CO}_2 + \text{MnO}_2 + \text{KOH} ]
