Question

Quizplus · Accepted Answer

The name of the compound is derived from the longest carbon chain, which contains five carbons. The carbonyl group is located on the second carbon and there are two methyl groups attached to the second carbon as well. Therefore, the IUPAC name is 2,2-dimethylpropanal. Option A is incorrect because pivaldehyde has a tert-butyl group attached to the carbonyl carbon. Option C is incorrect because tert-butyl aldehyde has a tert-butyl group attached to the carbonyl carbon, which is not the case in this compound. Option D is incorrect because there are only five carbons in the longest carbon chain, not six.
