Carbylamine test is used to detect the presence of a primary amino group in an organic compound. Which of the following compound is formed when this test is performed with aniline?
| 1. |  |
2. |  |
| 3. |  |
4. |  |
The correct statement about the given chemical reaction is :
1. -NH2 group is ortho and para directive, so product (B) is not possible.
2. Reaction is possible and compound (B) will be the major product.
3. The reaction will form sulphonated product instead of nitration.
4. Reaction is possible and compound (A) will be major product.
In the following reaction, the reason why meta-nitro product also formed is:
1. Low temperature
2. –NH2 group is highly meta-directive
3. Formation of anilinium ion
4. –NO2 substitution always takes place at meta-position
