An organic compound A reacts with sodium metal and forms B. On heating with conc. H₂SO₄, A gives diethyl ether. So A and B are:
1. C₃H₇OH and CH₃ONa
2. CH₃OH and CH₃ONa
3. C₄H₉OH and C₄H₉ONa
4. C₂H₅OH and C₂H₅ONa

Upon dehydration, the below mentioned compound will not give:

Ease of dehydration of the above alcohols will be in the order of:

The best method to prepare cyclohexene from cyclohexanol is by using:

What is the correct order of dehydration rate for the compounds (i), (ii), and (iii) when treated with concentrated \(\text{H}_2\text{SO}_4\)?

(i)
(ii)
(iii)

1. (i) > (iii) > (ii)                                             

2. (i) > (ii) > (iii)

3. (ii) > (i) > (iii)                                             

4. (ii) > (iii) > (i)

Optically active 2-octanol rapidly loses its optical activity when exposed to :
