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.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
