Interpretation Introduction

Interpretation:

The structures of the compounds, D, E and F are to be predicted for the given reaction scheme.

Concept introduction:

Ultraviolet-visible (UV-Vis) spectroscopy is when electromagnetic radiation is passed through a compound having multiple bonds, where some part of the energy is absorbed.

UV-Vis spectroscopy can differentiate between conjugated dienes and other unsaturated hydrocarbons or unconjugated dienes.

When an infra-red (IR) radiation is passed through a sample, the energy of the IR radiation is absorbed by the particle. Unlike UV-Vis, the electrons don’t jump to higher orbitals; instead, there is a change in the vibrational energy of the covalent bond within the molecule.

IR spectroscopy is used to find functional groups in a molecule.
