Q. The reaction in which phenol differs from alcohol is
A) It undergoes esterification with carboxylic acid
B) It reacts with ammonia
C) It forms yellow crystals of iodoform
D) It liberates $H_{2}\$with Na metal
Explanation
(c)
Iodoform test is given by those compounds which has
$CH_{3} - C - C/H\ or\ CH_{3} - CH -$ units.
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \parallel \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |$
O OH
Hence, this test is not given by phenol $\left( C_{6}H_{5} - OH \right).$
