1-Phenoxypropane is treated with an excess of conc. Hl at 0C and the mixture of products is treated with thionyl chloride. The products formed are:
| 1. | n-propanol + Chlorobenzene |
| 2. | Phenol + n-propyl iodide |
| 3. | n-propyl chloride + Chlorobenzene |
| 4. | n-propyl chloride + Phenol |
The order of reactivity of the following Compounds in electrophilic monochlorination at the most favourable position is
1. I < II < IV < III
2. III < IV < I < II
3. IV < III < II < I
4. III < II < IV < I
Select the correct option based on statements below:
| Assertion (A): | Phenol does not react with NaHCO3 but 2,4,6-trinitrophenol does react with the evolution of CO2 |
| Reason (R): | 2,4,6-trinitrophenol is a stronger acid than carbolic acid. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
