Interpretation:
A structure for the compound A, C8H10O2, with the following spectral data is to be proposed.
IR: 1750 cm-1; 13CNMR: 219 δ (20), two signals between 35 δ to 45 δ.
Concept introduction:
In 13CNMR, carbons in double bond which are sp2 hybridized absorb from 110 to 220 δ. Saturated aldehydes and ketones usually absorb in the region from 200 to 215 δ While aromatic and unsaturated carbonyl compounds absorb in the 190 to 200 δ region. The primary alkyl carbon absorbs in the range 10-15δ, a secondary alkyl radical in the range 16-25δ while a tertiary alkyl in the range 25-35 δ.
