Q. Identify the correct statements from the following
(i) Electromeric effect is a permanent effect
(ii) Hyper conjugation is a temporary effect
(iii) Fractional distillation is used to separate two liquids from a mixture if the difference in their boiling points is less
(iv) Different compounds are adsorbed on an adsorbent different extents

Solution:

(a) and (b) are incorrect statements as

(a) Electromeric effect is a temporary-effect, it only act when reagent is present and vanishes as reagent is removed.

(b) Hyper-conjugation is a permanent effect which allows delocalised electrons to move with or without presences of reagent.

Hence, only (c) and (d) are the correct statements
