Answer 1

Answer:

The product is Potassium Chromate

Explanation:

Answer 2

Answer:

b

Explanation:

first reaction: haloform —COOK then with H+

forms —COOH

now on heating we need to check for decarboxylation.

on the alpha carbon next to the C≈O of the —COOH, if a -ve charge on that alpha carbon is stabilized by resonance, then remove the —COOH group for CO2

hence you get B part as answer
