Give the structure of a compound that has a formula of C₄H₇ClO₂ and has a triplet (3H,1.1 ppm),quintet (2H,1.2 ppm),triplet (1H,4.4 ppm),and singlet (1H,11.6 ppm)in the ¹H NMR spectrum.

Question

Quizplus · Accepted Answer

The NMR spectrum indicates the presence of four different types of protons in the compound. The triplet at 1.1 ppm corresponds to three equivalent protons adjacent to one sulfur atom (S1U1P11), the quintet at 1.2 ppm corresponds to two equivalent protons adjacent to two boron atoms with one attached oxygen (B14OS), the triplet at 4.4 ppm corresponds to one proton adjacent to one sulfur atom (S1U1P11), and the singlet at 11.6 ppm corresponds to one proton attached to one boron atom (B0H). Only structure A has the correct arrangement of these groups to produce the observed NMR spectrum.
