Textbook Question

Chapter 21, Problem 21.10P

Draw the structure of all constitutional isomers that contain a ketone and have molecular formula C 5 H 10 O . Give the IUPAC name for each isomer and state how 13 C NMR spectroscopy could be used to distinguish these isomers.

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

Students have asked these similar questions

You have a sample of a compound of molecular formula C11H15NO2, which has a benzene ring substituted by two groups, (CH3)2N− and −CO2CH2CH3, and exhibits the given 13C NMR. What disubstituted benzene isomer corresponds to these 13C data?

Compound B has molecular formula C9H12. It shows five signals in the 1H-NMR spectrum - a doublet of integral 6 at 1.22 ppm, a septet of integral 1 at 2.86 ppm, a singlet of integral 1 at 5.34 ppm, a doublet of integral 2 at 6.70 ppm, and a doublet of integral 2 at 7.03 ppm. The 13C-NMR spectrum of B shows six unique signals (23.9, 34.0, 115.7, 128.7, 148.9, and 157.4). Identify B and explain your reasoning.

Name each compound and state how many lines are observed in its 13C NMR spectrum.

Draw the structure of all constitutional isomers that contain a ketone and have molecular formula C 5 H 10 O . Give the IUPAC name for each isomer and state how 13 C NMR spectroscopy could be used to distinguish these isomers.

Solution Summary: The author explains that Constitutional isomers have the same molecular formula, but different skeletal structures, and their IUPAC names are entirely different.
