Question

The effectiveness of a solvent can be measured by the
A.distribution coefficients
B. selectivity
C. both (a) and (b)
D. diffusivity

Answer 1

the ans is distribution coefficients not very sure

Answer 2

The effectiveness of a solvent can be measured by the distribution coefficients and selectivity.

so both (a) and (b) are correct.

Explanation:

Distribution coefficient:

The distribution coefficient is defined as the ratio of the concentration of solute in the organic phase over by the concentration of solute in the aqueous phase.

Selectivity

The selectivity is defined as the the ratio of the distribution coefficient of A to the distribution coefficient of B.

Where A and B are solvents .

There are three types of selectivity:

(i) Chemoselectivity

(ii) Regioselectivity

(iii) Stereoselectivity

Hence ,

option (c) both a and b is correct.
