Propane and Chlorine react in the presence of UV light to give 2-chloropropane and HCl. Estimate the enthalpy change of this reaction using the following bond enthaplies (KJ/mol) : C-H=+413, Cl-Cl=+243, C-Cl=+346 and H-Cl=+432.

Write equation, ensuring both sides are balanced.CH 3 CH 2 CH 3 + Cl 2 → CH 3 CH(Cl)CH 3 + HCl (2.) Draw structural formula of all reactants and products. (3.) Count the number of, and which types of bonds a...
