Question

Identify the product A and product B in the following set of reactions.

• A. A-CH$_3$CH$_2$CH$_2$OH ; B-CH$_3$CH$_2$CH$_2$CH$_2$OH
• B.
• C.
• D. A-CH$_3$CH$_2$CH$_3$, B-CH$_3$CH$_2$CH$_3$

Answer 1

Answer: (C)

Answer 2

(1) Hydration Reaction:

$CH_3 - CH = CH_2 + H^+ \rightarrow CH_3 - \overset{+}{C}H - CH_3 \; \text{(More stable)}$

(2) Hydroboration Oxidation Reaction:

$3CH_3 - CH = CH_2 + B_2H_6 \xrightarrow{\text{THF}} 2(CH_3CH_2CH_2)_3B$
$(CH_3CH_2CH_2)_3B + 3H_2O_2 \xrightarrow{\text{OH}^-} 3CH_3CH_2CH_2OH + H_3BO_3$ (B)

Thus the correct answer is Option 3.
