I'm studying for an organic lab I took and I'm trying to understand two things about four molecules behaving as solvents: water, dichloromethane, methyl tert-butyl ether, diethyl ether

1. Why is water more polar than dichloromethane?

2. Why is diethyl ether more polar than methyl tert-butyl ether?

Does this makes sense to you?

Start by thinking about what's the main difference between dichloromethane (CH3Cl2) and H2O in terms of solvation.

As for diethyl ether and methyl tertbutyl ether. You have to take into account that the tert butyl group is a large hydrophobic mass so it's less polar
