Chapter 16, Problem 16.58AP

Interpretation Introduction

Interpretation:

The structures of the compound $A$, $B$ and $C$ are to be stated.

Concept introduction:

Number of NMR signal in a compound is equal to the number of chemically non-equivalent protons present in that compound. The more the shielded proton, less will be its chemical shift value and the corresponding signal will be produced at the right-hand side or lower frequency region or vice versa.

Alkyl halides undergo elimination reaction to produce alkenes. In an unsymmetrical alkyl halide, the hydrogen atom is eliminated from the more substituted carbon atom. An alkene is reduced to alkanes by catalytic-hydrogenation reaction.
