Question

Which of the following is/are incorrect statement(s) about given compound?

• A. It gives coloured solution with neutral $FeC{l}_3$ solution
• B. It liberates half mole $H_2$ gas with $Na$ metal
• C. It gives +ve iodoform test
• D. It responds positively with Victor Mayer test

Answer 1

The correct option is D It responds positively with Victor Mayer test

(a)Compound has phenolic group so it gives violet or blue colouraration on treatment with freshly prepared $FeC{l}_3$ solution.

(b) $R-OH+Na\to R-ONa+H_2$
One mole of given compound on treatment with sodium metal produces half mole of hydrogen gas.

(c) Compound has $-\stackrel{O}{\stackrel{||}{C}}-C{H}_3$ moeity hence gives iodoform test.

(d) Phenol does not give Victor Mayer test.
