Question

The reaction \[ \mathrm{CH_3-CH=CH_2 \xrightarrow[\text{H}^+]{CO+H_2O} CH_3-CH(COOH)-CH_3} \] is known as:

• A. Wurtz reaction
• B. Koch reaction
• C. Clemmensen reduction
• D. Kolbe’s reaction

Hint:

Koch reaction converts alkenes into carboxylic acids using CO.

Answer 1

The Correct Option is B

Step 1: In Koch reaction, an alkene reacts with CO and water in acidic medium.
Step 2: This leads to formation of a carboxylic acid with increased carbon chain.
