Chapter 20, Problem 81IP

Interpretation Introduction

Interpretation:

The spectroscopic structure identification of given molecular formula should be draw and identified.

Concept Introduction:

NMR Spectroscopy: NMR spectroscopy commonly known as MRI (Magnetic Resonance Spectroscopy), it is important Research tool of analysis for different organic molecule and its structures (or) In other words hydrogen nuclei have spin (odd value) and all nuclei ae electrically charged. The extremal magnetic field is applied, some energy transfer is possible between the lower energy to excited level.

${}^{1}HNMR$Spectroscopy: The ${}^{1}HNMR$(or) single hydrogen (H) is the application of NMR spectra with respect to hydrogen nuclei within the molecules of a substance, in order to determine the structure of its molecules.

Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via $E1$(the reaction depends only on the substrate involved in the reaction) or $E2$(the reaction depends on both of the substituents in the reaction) mechanism.
