Hello Anurag

First of all, the lyophobic and the lyophilic, both are colloids.

But the main difference is that the lyophilic colloids are solvent loving colloids. Means, there is a strong attraction between the lyophilic colloids and the liquid.

Whereas, the lyophobic colloids are solvent hating colloids. There is less or no attraction between the lyophobic colloids and the liquid.

I hope, you understood :)

Hey anurag Kumar

Lyophilic colloids are liquid loving colloids (Lyo means solvent and philic means loving) where as  Lyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating).

Examples of Lyophilic are Sols of organic substances like gelatin, gum, starch and proteins.and Lyophobic  are Sols of inorganic substances like Arsenic (As ₂ S ₃ ), Iron (Fe(OH) ₃ ) and Platinum.

As lyophillic colloids are liquid loving, their sols are easy to prepare and can be prepared directly by mixing colloid with liquid. Additional stabilizers are not required during their preparation.

As these lyophobic colloids are water hating, their sols are easy to prepare and cannot be prepared directly by mixing colloid with liquid. Special methods are employed to prepare lyophobic sols and additional stabilizers are required during their preparation.

hope this helped

all the best
