Lewis structure along with bonding and isomerism in terms of Valence bond theory has to be explained. Concept Introduction: Valence bond theory: VSEPR theory tells about the shapes of molecules and ions by taking the consideration that the outermost electron pairs are arranged about each atom so that the pairs of electrons are kept at a distance from one molecule to other, thereby minimizing the repulsion of electron-pair. Lewis structure, otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom. To draw Lewis structure of N 2 H 2

Solution Summary: The author explains Lewis structure along with bonding and isomerism in terms of Valence bond theory.
Definition Definition Theory that explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. VBT gives a quantum mechanical approach to the formation of covalent bonds with the help of wave functions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.

Interpretation Introduction
Interpretation:
Lewis structure along with bonding and isomerism in terms of Valence bond theory has to be explained.
Concept Introduction:
Valence bond theory: VSEPR theory tells about the shapes of molecules and ions by taking the consideration that the outermost electron pairs are arranged about each atom so that the pairs of electrons are kept at a distance from one molecule to other, thereby minimizing the repulsion of electron-pair.
Lewis structure, otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

These are synthesis questions. You need to show how the starting material can be converted into
the product(s) shown. You may use any reactions we have learned. Show all the reagents you
need. Show each molecule synthesized along the way and be sure to pay attention to the
regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made
along the way, you need to draw both enantiomers and label the mixture as "racemic".
All of the carbon atoms of the products must come from the starting material!
