Interpretation Introduction

Interpretation:

A pair of chain propagation steps for the radical bromination of propane to give 1-bromopropane has to be written and ΔH0 for propagation steps and overall reaction has to be calculated.

Concept introduction:

Halogenation of alkanes: The replacement of one or more hydrogen atoms by halogen. When alkanes is heated or irradiated with the light of specific wavelength, the alkyl halide are formed by radical chain reaction.
