A single chemical bond , a double bound a triple bound according to the three major bonding theories Lewis model, valance bond theory and molecular orbital theory is similar or different. Concept Introduction: According to Lewis theory, a bond is formed by sharing of a pair of electrons between two atoms. So, a double and triple bond involve sharing of four and six electrons, respectively, between the two atoms. Bond theory says that the sigma overlap of two orbitals forms a single bond. A double bond is asigma bond accompanied by a pi bond while a triple bond is a sigma bond accompanied by twopi bonds. The molecular orbital theory defines a single, double, and triple bond in terms of bond orders of 1, 2, and 3 between the two atoms. This bond order is calculated from the number of electrons in thebonding and antibonding molecular orbitals in the molecular orbital diagram.

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: A single chemical bond, a double bound a triple bound according to the three major bonding theories Lewis model, valance bond theory and molecular orbital theory is similar or different.
Concept Introduction:
According to Lewis theory, a bond is formed by sharing of a pair of electrons between two atoms. So, a double and triple bond involve sharing of four and six electrons, respectively, between the two atoms.
Bond theory says that the sigma overlap of two orbitals forms a single bond. A double bond is asigma bond accompanied by a pi bond while a triple bond is a sigma bond accompanied by twopi bonds.
The molecular orbital theory defines a single, double, and triple bond in terms of bond orders of 1, 2, and 3 between the two atoms. This bond order is calculated from the number of electrons in thebonding and antibonding molecular orbitals in the molecular orbital diagram.
Using the graphs could you help me explain the answers. I assumed that both graphs are proportional to the inverse of time, I think. Could you please help me.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
