Find double bond equivalence: DBE = C+1-H/2-X/2+N/2

DBE = 9+1-4:

DBE = 5. This means total 5 double bonds in the compound in the compound. One should be aromatic group.

If we see 1H nmr and IR there is an aldehyde group and ethelene present on the aromatic ring. A singlet at 7.18 shows both substituted in meta position to each other.

Signal	Chemical shift	Multiplicity	No. of Hydrogens
a	5.25	Dd, J = 16, 13	1H (alkene)
b	5.76	Dd J = 16, 0.9	1H (alkene)
c	6.72	Dd J = 13, 0.9	1H (alkene)
d	7.18	singlet	aromatic
e	7.48	triplet	aromatic
f	7.76	doublet	aromatic
g	7.88	doublet	aromatic
h	9.88	singlet	Aldehyde proton

IR values:

1700- aromatic aldehyde group

1600, 1200- alkene group

750, 2900- aromatic SP2 hydrogens
