The reaction of phenol with chloroform in the presence of dilute sodium hydroxide finally introduces a functional group X. The X is:
1. -CH2Cl
2. -COOH
3. -CHCl2
4. -CHO
1. | 2. | ||
3. | 4. |
The most acidic compound among the following is:
1. | 2. | ||
3. | 4. |
Among the following four compounds
a. | Phenol | b. | methyl phenol |
c. | meta-nitrophenol | d. | para-nitrophenol |
The acidity order is:
1. c > d > a > b
2. a > d > c > b
3. b > a > c > d
4. d > c > a > b
Phenol in a set of reactions (as captured below) yielded a product Z.
\(\text{Phenol}\ \xrightarrow{\text{Zn Dust}}\ \text{X}\ \xrightarrow[\text{Anhy. }{AlCl_3}]{CH_3Cl}\ Y\)
\( Y\ \xrightarrow[KMnO_4]{\text{Alkaline}}\ Z\)
The structure of the product Z would be:
1. Toluene
2. Benzaldehyde
3. Benzoic acid
4. Benzene
