Preparation Methods of Haloalkanes and Haloarenes
Study the various laboratory and industrial methods for preparing haloalkanes and haloarenes, including special named reactions.
Why this shows up in the exam
You need to recognize and predict products of key synthetic routes in exams.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
The following reaction method is not suitable for the preparation of the corresponding haloarene products, due to higher reactivity of halogen, when X is
Push further
More challenging9 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
The addition of HCl to 1-butene yields primarily:
