Why is dimethylformamide a polar aprotic solvent?

Answer 1

Ava Andrews

Dimethylformamide is a polar aprotic solvent because it is a polar molecule and has no OH or NH groups.

The structure of dimethylformamide is

The polar C=O and C-N bonds make the molecule polar.

There are no O-H or N-H bonds, so the molecule is aprotic.

So, dimethylformamide is a polar aprotic solvent.

Dimethylformamide (DMF) is polar because it contains polar bonds (C=O and C-N) due to differences in electronegativity between carbon, oxygen, and nitrogen atoms. It is aprotic because it lacks an acidic hydrogen atom bonded directly to an electronegative atom.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
