1)
It is very easy to assign protons based on splitting.
triplet, 1H means CH-CH2- fragment
singlet, 6H means two methyl groups are isolated
doublet, 2H means -CH2-CH- group
singlet, 3H means a methyl group -CH3 is isolated.
2)
The given spectrum belongs to 3-Methylbutyl formate (also called as Isopentyl formate)
the correct assignments are also shown.
Hope this helped you!
