Question

Identify number of reactions that would give salicylic acid as major product.

• A. 6
• B. 5
• C. 4
• D. 3

Answer 1

Answer: (D)

Three reaction, (b), (c) and (e) would give salicylic acid as major product.
Reaction (a) is Reimer-Tiemann reaction and would give Salicyaldehyde as major product.
Product in (a) is:

Reaction (b) is Kolbe Schmitt reaction, and would give salicylic acid as major product.
Product in (b) is:

Reaction (c) is extension of Reimer-Tiemann reaction and give salicylic acid as major product.
Reaction (d) is Reimer-Tiemann reaction and give salicyaldehyde as major product.
Reaction (e) is oxidative ozonlysis:

Hence the answer is:
Three reactions $(b,c$ and $e)$ would give salicylic acid as major product.
