?1. What is the IHD for the compound. 2. What is the structure of the compound. 3. What protons give the difenrent signals (assigning peaks).
Homework Answers
Formula for IHD is Compound (CxHy): IHD= (2x + 2 - y)/2
Hence for C8H10O = (16 + 2 -10)/2 = 4 Hence compound has 4 sites of unsaturation but compound is aromatic by NMR hence Compound must be substituted benzene derivative. By NMR it’s clear that compound has CH3 group and CH group and OH group. The possible structure is as follows.
Following protons gives different peaks in NMR.
