An unknown alcohol is treated with the “Lucas reagent” to determine whether the alcohol is primary, secondary or tertiary. Which alcohol reacts the fastest and by what mechanism:

1. secondary alcohol by S_N²

2. tertiary alcohol by S_N²

3. secondary alcohol by S_N¹

4. tertiary alcohol by S_N¹

The compound that does not react with sodium is-

1. CH₃CHOHCH₃

2. CH₃ —O—CH₃

3. CH₃COOH

4. C₂H₅OH

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

Phenol on treatment with dil. HNO₃ at room temperature gives-

1.
2.
3.
4.	All of the above

Identify A and predict the type of reactions


1.   and substitution reaction

2. and elimination addition reaction

3.   and cine substitution reaction

4.      and cine substitution reaction

Identify A, X, Y and Z 

(1) A-methoxymethane, X-ethanoic acid, Y-acetate ion, Z-hydrazine

(2) A- methoxymethane, X-ethanol, Y-ethanoic acid, Z- semicarbazide

(3) A-Acetaldehyde, X-ethanol, Y-but-2-en-1-ol, Z- semicarbazone

(4) A-ethanol, X-acetaldehyde, Y-butanone, Z-hydrazone

Which one is the most acidic compound ?

The reaction 

can be classified as
