Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Chemical Sciences Structure Determination of Organic Compounds 1h NMR and 13c NMR Spectroscopy
The reaction of PCl3 with methanol in the preence of triethylamine affords compound X. EI mas spectrum of X shows a parent ion peak at m/z = 124. Microanalysis of X shows that it contains C, H, O and P. The 1H NMR spectrum of X shows a doublet at 4.0 ppm. The sepraration between the two lines of the doublet is approximately 15 Hz (I for for 1 H and 31P = ½)
Compound X is:
1
(CH3O)3P
2
(CH3O)2P
3
(CH3O)2P(O)(OH)
4
(CH3O)3PH
5
