Self condensation of two moles of ethyl acetate in presence of sodium ethoxide yields :

1. Ethyl butyrate

2. Acetoacetic ester

3. Methyl acetoacetate

4. Ethyl propionate

Nucleophilic addition reaction will be most favoured in-

1. $C{H}_{3}C{H}_{2}C{H}_{2}COC{H}_3$

2. $(C{H}_3{)}_{2}C=O$

3. $C{H}_{3}C{H}_{2}CHO$

4. $C{H}_{3}CHO$

A carbonyl compound reacts with hydrogen cyanide to form cyanohydrins which on hydrolysis forms a racemic mixture of α-hydroxy acid. The carbonyl compound is :

1. Acetaldehyde

2. Acetone

3. Diethyl ketone

4. Formaldehyde

In a set of reactions propanoic acid yielded a compound D. 

${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{COOH}\stackrel{{\mathrm{SOCl}}_2}{\to }\mathrm{B}\stackrel{{\mathrm{NH}}_3}{\to }\mathrm{C}\underset{{\mathrm{Br}}_2}{\overset{\mathrm{KOH}}{\to }}\mathrm{D}$ 
The structure of D would be :

1. $C{H}_{3}C{H}_{2}C{H}_{2}N{H}_2$

2. $C{H}_{3}C{H}_{2}CON{H}_2$

3. $C{H}_{3}C{H}_{2}NHC{H}_3$

4. $C{H}_{3}C{H}_{2}N{H}_2$

The product formed in aldol condensation is :

Consider the following compounds : 
(i) C₆H₅COCl 
(ii)  

(iii)  

(iv)  

The correct decreasing order of their reactivity towards hydrolysis is :

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

2. (i)>(ii)>(iii)>(iv)

3. (iv)>(ii)>(i)>(iii)

4. (ii)>(iv)>(i)>(iii)
