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

Widespread deaths due to liquor poisoning occur due to the presence of-

1. Lead compounds in liquor

2. Methyl alcohol in liquor

3. Ethyl alcohol in liquor

4. Carbonic acid in liquor

Upon dehydration, the below mentioned compound will not give -

1.		2.
3.		4.

Consider the following alcohols,

I.
II.
III.
IV.

Ease of dehydration of the above alcohols will be in the order of-
1. I < II < III < IV 
2. I > II > III > IV
3. III  < II < I < IV
4. II < III < IV < I

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

1. conc. HCl + ZnCl₂                     

2.  conc. H₃PO₄

3. HBr

4. conc. HCl

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)
