CH2101 (a) Compound X gives combustion analysis data C-439 %, H-66% CI-26.0 % and O-23.5 % The molecular weight of X is 136.5 g mol IR analysis of compound X reveals a strong absorbance at 1736 om In the 'H NMR spectrum of compound X (Spectrum Q1), the numbers by each signal refer to the integral height. All non-singlet signals are expanded below the main spectrum and the appropriate coupling constants reported below each expansion Spectrum Q1 as 2.5 2.0 1.5 10 8/ppm Lu 6/ppm J = 7.1 H₂ 3.82 3.80 8/ppm J = 6.3 Mz &/ppm J= 6.3 Hz 1.16 1.14 & /ppm 17.1 H With the aid of the chemical shift data (see special resources file on Blackboard) interpret Spectrum Q1 and identify the structure of compound X.
