(a)

Interpretation Introduction

INTREPRETATION:

The product formed for the reaction between fumarate and $H_{2}O$ in presence of catalyst $H_{2}S{O}_4$ should be determined.

CONCEPT INTRODUCTION:

Nucleophile: Nucleophiles are electron rich compounds which donates electrons to electrophilic compounds which results in bond formation.

Nucleophilic nature depends on the negative charge present in the molecule, the solvent in which it present and the electronegativity of the atom.

Electrophile: Electrophiles are electron deficient compounds which accepts electrons from nucleophiles that results in bond formation.

Chemical reaction involves bond making and breaking of two or more reactants in order to attain products from the reactants.

The curved arrows are generally used to indicate the flow of electrons present in the reaction.

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.

In addition reaction of alkenes when two substituents are placed on same side of $C=C$ then it is named as $syn$ addition if it is placed on opposite sides of $C=C$ it is defined as anti-addition.

Oxidation Reaction: It involves loss of electrons, addition of oxygen atoms or removal of hydrogen atoms.

Oxidizing Reagents: The chemical agents used to add oxygen or remove hydrogen which finally reduced on oxidizing the other compound.

Carbocation: it is carbon ion that bears a positive charge on it.

Carbocation stability order:

Enantiomers: they are chiral molecules whose mirror images are not superimposable.

R and S nomenclature: it is used to assign the molecule using CIP rules.

The CIP rules are as follows:

Select the chiral carbon and assign the numbers according to the decreasing atomic mass of atoms attached to it.

If the numbering follows clockwise direction then the molecule is termed as R and if it follows anti-clockwise direction then molecule is termed as S.
