Alkyl bromide used in the acetoacetic ester synthesis of each methyl ketone has to be stated. Concept introduction: Acetoacetic ester synthesis is used to prepare methyl ketone of the desired length. The acetoacetic ester is reacted with an alkoxide base which removes a α hydrogen atom. The anion so formed is reacted with an alkyl bromide. The anion abstracts the alkyl group from the alkyl bromide. Acidic hydrolysis of the intermediate so formed on heating undergo decarboxylation which gives the desired methyl ketone.

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right.
