4.18—The mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are

Understand the mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are species with an unpaired electron, represented by a single dot ii showing the initiation step of the mechanism, with curly half-arrows for free radical formation iii showing the propagation and termination steps of the mechanism iv having limited use in synthesis because of further substitution reactions.

Use —the mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are to connect the rule to the data and decision in the question.

This matters because —the mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
