Compound has a composition a 68.2% C, 13.6% H and 18.2% O by mass.
IR
- A notable feature of the 1H spectrum is a multiplet of nine at d1.7.
A splitting pattern of nine peaks must be produced by eight adjacent protons (8+1)
- The 13C spectrum shows the reference peak and four peaks
13C Spectrum
Peak is due to the carbon atom in position d as it has a chemical shift of d60.7 (corresponds to a -C-O- functional group) and is connected to an even number of protons (2).
Peak is due to the carbon atom in position c as it has a chemical shift of d41.5 (corresponds to a secondary carbon group) and is connected to an even number of protons (2).
Peak is due to the carbon atom in position b as it has a chemical shift of d24.6 (corresponds to a tertiary carbon group) and is connected to an odd number of protons (1).
Peak is due to the two carbon atoms in position a as it has a chemical shift of d22.5 (corresponds to a primary carbon group). It can be seen that the carbon atoms are also connected to an odd number of protons (3).
