Question:medium
Number of distinct NMR signals observed in case of acetone and ethyl methyl ketone are:
Number of distinct NMR signals observed in case of acetone and ethyl methyl ketone are:
Show Hint
The number of distinct NMR signals corresponds to the number of non-equivalent hydrogen environments in the molecule.

- 1 and 3
- 2 and 3
- 2 and 5
- 1 and 2
Show Solution
The Correct Option is A
Solution and Explanation
Acetone exhibits \(1\) unique NMR signal, corresponding to the methyl group. Conversely, ethyl methyl ketone displays \(3\) distinct signals: one for each methyl group and one for the hydrogen atom adjacent to the carbonyl group.
