Answer 1

Your compound seems to be 1,2-dihydrostilbene IR shows aromatic stretching peaks at around 1500 cm 13C NMR CH, at 38 ppm, Aromatic Carbon at 125-130 ppm, and the substituted carbon at 140ppm. 1H NMR showed two peaks. i e. sing let at 2.9 ppm 4 equivalent methylene protons. In mass spectrum characteristic tropylium ion peak shows the presence of benzylic position
