Expert Solution
Step 1

The double bond equivalent for the compound is equal to 1. This suggests the presence of carbonyl group. The 10 hydrogens are divided into two sets, one set consists of six hydrogens and other consists of 4 H. Chemical shift at 1.0 ppm with triplet splitting indicates the presence of methyl group. Chemical shift at 2.4 ppm with quadrate splitting indicates the presence of methylene group. The higher increment of methylene group (base peak at 1.2 ppm) is due to the presence of carbonyl group.
