JEE Main levelSingle correct optionDifficulty 2 of 3si240

How many 1H NMR signals does the compound shown give? Chemically equivalent hydrogens give one signal; ignore coupling and axial/equatorial differences.

A $3$
B $4$
C $5$
D $6$

Answer: B

The compound shown is methyl 4-methylbenzoate:

OCH X_{3}

, aryl

CH X_{3}

and two sets of aromatic H, so 4 signals.
