Question

A compound ‘A’ (molecular formula C3H6O2) reacts with sodium metal to
form compound ‘B’ and evolves a gas which burns with a pop sound. The
compound ‘A’ on treatment with alcohol ‘C’, found in beer, in presence of
concentrated sulphuric acid, forms a sweet smelling compound ‘D’
(molecular formula C5H10O2). On addition of NaOH to ‘A’ it also gives ‘B’
and water. ‘D’ on treatment with NaOH gives back ‘B’ and ‘C’. Identify
‘A’, ‘B’, ‘C’ and ‘D’ and write down the chemical equations of the reactions
involved.

Answer 1

Explanation:

Coordinating water policies are typically developed or led by the water sector, which, in turn, is assumed to have within it the actors whose policies and activities are most in need of coordination.

Answer 2

Identify  ‘A’, ‘B’, ‘C’ and ‘D’ and write down the chemical equations of the reactions  involved

Explanation:

A: Propionic acid $CH_{3}CH_{2}COOH$

B: Sodium salt of propionic acid

C: Ethanol CH3CH2OH

D: Ethyl Propanoate - An ester

$CH_{3}CH_{2}COOH + Na --> CH_{3}CH_{2}COONa+ H_{2}$

$CH_{3}CH_{2}COOH + C_{2} H_{5}OH + H^{+} --> CH_{3}CH_{2}COOC_{2}H_{5}+ H_{2}O$

$CH_{3}CH_{2}COOH + NaOH --> CH_{3}CH_{2}COONa+ H_{2}O$

$C_{2} H_{15}COOC_{2}H_{5} + NaOH --> C_{2}H_{5}COONa + C_{2}H_{5}OH$
