2. 3º < 2º < 1º
3. 3º > 2º < 1º
4. 3º < 2º > 1º

The increasing order of hydrolysis of the following compounds:

(1) (i)<(iii)<(ii)

(2) (ii)<(iii)<(i)

(3) (ii)<(i)<(iii)

(4) (i)<(ii)<(iii)

Read the following road map carefully

(1) Both the ethers obtained by the two routes have opposite but equal optical rotation.

(2) One of the ether is obtained as a racemic mixture.

(3) Step II & III both are SN2 reaction and both have inversion.

(4) Step II has inversion but step III has retention.
