Question

Give reasons

Mgcl2 is soluble in water but insoluble in acetone, while methane is insoluble in water,but soluble in acetone.

MgCl₂ is an ionic and thus polar compound.So, it dissolves in polar water but insoluble in non- polar acetone.

Whereas, methane being non-polar dissolves in a non-polar acetone and is insoluble in polar water.
