How many singlets will the ¹H NMR spectrum of 2 -bromo- 3 -methyl-2-butene exhibit?

Question

Quizplus · Accepted Answer

The compound 2-bromo-3-methyl-2-butene has a structure that can be simplified as follows: a bromine atom attached to a carbon that is part of a double bond, with a methyl group (CH3) on the adjacent carbon. The remaining carbons in the double bond and the methyl group are unique environments for hydrogen atoms. There are three unique sets of hydrogen environments: the hydrogens on the methyl group attached to the double bond, the hydrogen on the carbon adjacent to the bromine, and the hydrogens on the methyl group at the end of the molecule. Each of these environments will give rise to a singlet in the NMR spectrum because there are no neighboring hydrogens to split their signals (considering the simplification for this specific question's context).
