MHT CET 2025 Chemistry question

Propene on hydroboration followed by oxidation with alkaline peroxide forms.

(A)Tri-n-propylborane
(B)Tri iso propylborane
(C)Propan-1-olCorrect
(D)Propan-2-ol

Answer: (C)

Solution

Hydroboration-oxidation adds water across the double bond with anti-Markovnikov orientation. Step 1: 3CH_3CH=CH_2 + B_2H_6 \rightarrow 2(CH_3CH_2CH_2)_3B (tri-n-propylborane); boron attaches to the less hindered terminal carbon. Step 2: oxidation with alkaline hydrogen peroxide
