Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Chemical Sciences Structure Determination of Organic Compounds 1h NMR and 13c NMR Spectroscopy
Upon heating, comopund X is converted to Y, which has the same molecular formula as that of X. The 1H NMR spectrum of Y shows two doublets centered at 3.0 ppm (separation of two lines ~ 20 Hz) and 4.0 ppm (separationg of two lines ~ 15 Hz) respectively:
Compound Y is:
1
(CH3O)2 P(O)(OH)
2
(CH3O)3P(O)
3
(CH3O)2(CH3)P(O)
4
(CH3O)2(CH3)P(OH)
