JEE Main levelOne or more correct optionsDifficulty 2 of 3o1027

Which of the following are polar aprotic solvents?

Aacetone, $CH X_{3} - CO - CH X_{3}$
BN,N-dimethylformamide, $HCON (CH X_{3}) X_{2}$
Cmethanol, $CH X_{3} OH$
Dethanoic acid, $CH X_{3} COOH$

Answer: A, B

Aprotic solvents have no hydrogen bonded to oxygen or nitrogen. Acetone and DMF are polar but lack such hydrogens. Methanol and ethanoic acid have O-H bonds and are protic.
