1. C₃H₇OH and CH₃ONa
2. CH₃OH and CH₃ONa
3. C₄H₉OH and C₄H₉ONa
4. C₂H₅OH and C₂H₅ONa

Among the following ethers, the one that will produce methyl alcohol on treatment with hot concentrated HI is:

1.		2.
3.		4.

The correct order of dehydration of compounds (i), (ii) and (iii) by conc. H₂SO₄ is:

(i)
(ii)
(iii)

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

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

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

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