Methanol cannot be dried with anhydrous CaCl2 because
CaCl2 dissolves in it
it is not good dehydrating agent
It forms as solid CaCl2 · 4CH3OH
it reacts with CH3OH
C.
It forms as solid CaCl2 · 4CH3OH
Methanol cannot dried with anhydrous CaCl2 because it forms a solid CaCl24CH3OH (addition compound).
The correct order of ease of dehydration of following is:
I > II > III
III > II > I
I > III > II
III > I > II
