Question

Given are the isomers $C_8{H}_8{O}_2$.
Which isomer gives $+$ive Tollen's test, also reacts with $FeC{l}_3$?

• A. b
• B. f
• C. c
• D. d

Answer 1

Answer: (B)

f

As aldehydes gives positive Tollen's test, so the isomer may be

(Refer to Image 1)

But between (a) & (b), b will not react eith $FeC{l}_3$ as it has phenolic-O-H$ group

(Refer to Image 2)

But (Refer to Image 3) $⟶$ It does not give phenoxide and hence does not react with $FeC{l}_3$

So, the answer is (Refer to Image 4) .
