Q.5. What is the most likely molecular formula of a compound with m/z of 101 for its molecular ion, and m/z of 30 for its base peak in its EI mass spectrum. Write two isomers of this compound (more isomers are possible).
A compound used as a moth repellant has three molecular ion peaks at m/z = 146 (100%), 148 (65%) & 150 (10%) amu in its mass spectrum. A pair of smaller peaks are seen at m/z= 111 (34%) & 113 (11%). The infrared spectrum shows sharp absorption just above 3000 cm^-1 region, and also at 1480 cm^-1. The ^1 H nmr shows a single sharp signal at delta = 7.2 ppm, and the ^13 C nmr has two signals (delta = 133 & 130 ppm).
