In the IR there is a peak at: 2960, 2930, and 2860 (CH stretch), a small peak at 2720, and a strong peak at 1725(carbonyl stretch C=O)
In the NMR there is a peak at: singlet(1 Hydrogen at 9.5), triplet( 2 hydrogens at 2.5), quintet(2 hydrogens at 2), quintet or sextet( not clear)(4 hydrogens at 1.3), and triplet ( 3 hydrogens at 1).
The molecular formula is at C6H12O
