Radical substitution of alkanes with halogens

Pentane reacts with bromine, $\ce{Br2}$, to form 2-bromopentane. (i) Explain, using equations, the initiation step and two propagation steps for this reaction. (ii) State one termination step for this reaction.

Which equation represents a propagation step in the radical substitution of ethane by bromine? A. $\ce{Br2 -> 2Br•}$ B. $\ce{•C2H5 + Br• -> C2H5Br}$ C. $\ce{C2H6 + Br• -> C2H5Br + H•}$ D. $\ce{•C2H5 + Br2 -> C2H5Br + Br•}$

(i) Oil of vitriol, spirit of hartshorn and wood alcohol are old trivial names still occasionally used for chemical substances, and names like these can be a source of confusion in international scientific communication. Outline how the modern system of naming…

Methane reacts with chlorine in the presence of ultraviolet light. Two observations about this reaction are listed. - Observation 1: in the initiation step, $\ce{Cl-Cl}$ bonds undergo homolytic fission but $\ce{C-H}$ bonds do not. - Observation 2: the…
