CHM 2212-Organic Chemistry II Practice quiz #4February 7, 2002Practice Quiz #4 (Dr. Bausch; covering material thru section 13.7)1. A hydrocarbon of formula C4H10 was treated with NBS and the product isolated. The 1H NMR and mass spectra of the product is given below. Drawthe structure of the product and the starting material.1Note: this mass spectrum is not showing any molecular ion peaks! The peaks athigh m/z result from a loss of 15 from the molecular ions.22. Compound A (C4H8) undergoes a reaction to give B:A BC4H8The following IR, 1H NMR, and mass spectra are for B. Determine the structure of A and B, as well an appropriate reagent for the transformation.3Note, this mass spectrum is not showing anything for the molecular
