Haloarenes and Polyhalogen Compounds

Name: Haloarenes and Polyhalogen Compounds
Author: StemPy Lab

A halogen on a benzene ring behaves differently from one on a chain. Preparation and properties of haloarenes, why they resist nucleophilic substitution, their electrophilic substitution and coupling reactions, Grignard reagents, and the uses and environmental harm of chloroform, iodoform, tetrachloromethane, freons and DDT. It covers the Indian syllabus (NCERT, NEET, JEE Main) and the matching topic of A-Level, IB and AP.

Lesson 1about 25 min
Preparing haloarenes and their properties
Mothballs and some toilet blocks are made of a haloarene. These compounds are made in two ways: by putting a halogen directly on the ring, or by replacing the nitrogen of a diazonium salt. Here you learn both, and why the isomers differ in melting point.

Lesson 2about 30 min
Reactions of haloarenes
A chlorine atom on a chain is easily replaced, but on a ring it is hard to move. And yet the ring reacts with electrophiles, and the halogen sends the new group to certain positions only. This lesson explains both and adds the coupling reactions and the Grignard reagent.

Polyhalogen compounds and the environment
A bottle of chloroform, a can of paint remover and a refrigerator gas all belong to one family. Each has more than one halogen on a single carbon. Here we learn how they are made, what they are used for, and why some of them harm people and the planet.
