Which is NOT a polar aprotic solvent? (A)acetone (B) acetonitrile (C)DMF (D)methanol
In polar aprotic solvents no Hydrogen atom attached directly to the electronegative atoms that is oxygen, nitrogen etc.
In above example A) acetone B) Acetonitrile C) DMF no Hydrogen directly attached to the electronegative atom.that is these are the examples of polar aprotic solvent.
D) metanol - Hydrogen is directly attached to the oxygen atom hence not polar aprotic solvent,that is polar protic solvent.
Option - D
