The structure for the compound C is to be proposed. Concept introduction: DEPT stands for distortion less enhancement by polarization transfer. DEPT 13 C − NMR is used to indicate the number of hydrogen atoms that are bonded to each carbon while providing the information of chemical shift in a broadband proton-decoupled 13 C − NMR spectrum. The carbon signals in a DEPT spectrum are classified as CH 3 , CH 2 , CH or C accordingly. Presence of the electronegative compounds like halogens or oxygen or sulfur elements will downfield the signal i.e., the chemical shift will occur at higher δ than the unsubstituted carbons. The tollens test is used to distinguish between aldehyde and ketone . Aldehyde gives positive tollens test and ketone gives negative test.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
