Arrange following compounds in decreasing order of reactivity for hydrolysis reaction Question

(A) 3 > 1 > 2 > 4 (B) 2 > 4 > 3 > 1 (C) 2 > 4 > 1 > 3 (D) 1 > 3 > 4 > 2

Reactivity propto electron deficiency at C-atom of -CO group or Reactivity propto (1/S t a b i l i t y o f p o l a r s t r u c t u r e) Thus electron withdrawing group increases reactivity and electron donating group decreases reactivity. Hence the order is 2 > 4 > 1 > 3.

Q. Arrange following compounds in decreasing order of reactivity for hydrolysis reaction

3 > 1 > 2 > 4

2 > 4 > 3 > 1

2 > 4 > 1 > 3

1 > 3 > 4 > 2

Reactivity $\propto$ electron deficiency at C-atom of $- CO$ group

or Reactivity $\propto \frac{1}{St abi l i t y o f p o l a r s t r u c t u re}$

Thus electron withdrawing group increases reactivity and electron donating group decreases reactivity.

Hence the order is 2 > 4 > 1 > 3.
