10.17—The reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents • PCl5 to produce chloroalkanes

Understand the reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents PCl5 to produce chloroalkanes (including its use as a qualitative test for the presence of the –OH group) 50% concentrated sulfuric acid and potassium bromide to produce bromoalkanes red phosphorus and iodine to produce iodoalkanes iii concentrated phosphoric acid to form alkenes by elimination Descriptions of the mechanisms of these reactions are not required.

Use —the reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents • pcl5 to produce chloroalkanes to connect the rule to the data and decision in the question.

This matters because —the reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents • pcl5 to produce chloroalkanes determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents • pcl5 to produce chloroalkanes to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The reactions of alcohols with: i oxygen in air (combustion) ii halogenating agents • PCl5 to produce chloroalkanes is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
