The balanced chemical equation for the reaction of phosphorus with chlorine to form P C l 3 has to be determined. Concept Introduction: In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product. Coefficient is a number placed before a formula in a chemical equation. A balanced equation should be obeying the law of conservation of mass. Law of conservation of mass states that, the number of atoms remains constant throughout the reaction, simply it can be stated as follows, “during a chemical reaction atoms are neither be created nor be destroyed”.

Interpretation Introduction
Interpretation:
The enthalpy change of the reaction of P4 and Cl2 to PCl3 has to be determined.
Concept Introduction:
Bond energy or more correctly the bond dissociation enthalpy is the enthalpy change when breaking a bond in a molecule with the reactant and products in the gas phase.
ΔrH=∑ΔH(bondsbroken)−∑ΔH(bondsformed)
Enthalpy of formation:
ΔrH=∑ΔfH0(products)−∑ΔfH0(reactants)

6) The synthesis generates allethrolone that exhibits high insect toxicity but low mammalian toxicity. They are used in pet
shampoo, human lice shampoo, and industrial sprays for insects and mosquitos. Propose detailed mechanistic steps to
generate the allethrolone label the different types of reagents (Grignard, acid/base protonation, acid/base deprotonation,
