Question

Describe the number of signals and their splitting in the 1H NMR spectrum of (CH₃)2CHOCH₃.

Answer 1

The 1H NMR spectrum of (CH3)2CHOCH3 would show multiple signals due to the different types of hydrogen atoms present in the molecule.

Step-by-step explanation:

The 1H NMR spectrum of (CH3)2CHOCH3 would show multiple signals due to the different types of hydrogen atoms present in the molecule. Let's break it down:

1. The CH3 groups on the ends will each produce a single signal, since all of the hydrogen atoms in each group are chemically equivalent.

2. The CH group in the middle will produce a singlet signal, since there are no neighboring hydrogen atoms to cause splitting.

3. The CH2 group next to the carbonyl group will produce a triplet signal, due to the two neighboring hydrogen atoms.

So, in total, there will be 5 signals in the 1H NMR spectrum of (CH3)2CHOCH3: two singlets, one triplet, and two methyl groups giving two more singlets.
