Exam
Haloalkanes introduces organic compounds containing halogen atoms attached to alkyl groups. Students study their nomenclature, classification, isomerism, preparation and physical properties, followed by substitution, elimination, reduction and other important reactions of haloalkanes.
This page covers Haloalkanes, chapter 9 of 22 in the Class 12 Chemistry syllabus set by the National Examination Board (NEB). 4 important questions for this chapter are available, each with a full solution.
For numerical and derivation-based chapters like this one, working through past NEB questions is usually more useful than re-reading notes alone — try solving each important question above before checking the solution, then compare your working step by step.
