The unknown is 6-methyl-5-hepten-2-one
IR:
2967 & 2915 cm-1, medium are due to sp3 alkane C-H stretch
1715 cm-1, strong is due to aliphatic ketone C=O stretch
1356 cm-1, medium is due to sp3 alkane C-H bending
852 cm-1, medium is due to sp2 alkene =C-H bending
Mass: Molecular ion peak at m/z 126, base peak (most abundant peak) at m/z 43
HNMR & CNMR:
Assigned peaks of protons and carbons are in below image
