Q.


The compound (B) is:

Alcohols Phenols and Ethers Report Error

Solution:

i. (A) gives colour with , suggesting phenolic group.
ii. (A) gives positive Tollens reagent test, suggesting (-CHO) group.
iii. (A) contains only one group, since it reacts with of to form mono methyl ether.
iv. (A) is not steam distilled, which suggests that and (-CHO) groups are not in -position.
v. Total atom and atom, (benzene) group.
vi. Formula of
vii. To count for one additional atom and one additional atom, group must be present in (A).
viii. A must contain



But the compound contains , which is only possible with compound (II). Therefore, structure (A) is (II).
Reaction

Alternative method of solving the problem:
Start from (D) and proceed reverse to (C). (D) is obtained from (C) by HI, so two structures are possible for (A).

So, (A) is II and then proceed to find out other products.
