Chemistry Revision Notes for Class 12 Chapter 10 Haloalkanes and Haloarenes

Students of class 12 can now quickly revise their chemistry chapters before the exam. Below we have briefly discussed on Chapter 10 – Haloalkanes and Haloarenes which is easy to access for a quick revision. Halogen derivatives are classified as mono, di, tri, tetra, etc. based on the number of halogen atoms present. Based on the number of halogen atoms attached to the carbon, the derivatives of halogen are classified as primary, secondary, tertiary, aryl derivatives, etc.

Different methods of preparing Haloalkanes are:

  • From alcohols
  • From hydrocarbons
  • Halogen exchange

Different methods of preparing Haloarenes are:

  • By electrophilic substitution
  • By Sandmeyer’s reaction

Having strong basics in subjects like math and science is very important to excel in the fields of technology and science.

Frequently asked Questions on CBSE Class 12 Chemistry Notes Chapter 10: Haloalkanes and Haloarenes


What is ‘Halogen exchange’?

Halogen exchange reactions are those reactions in which one halide replaces another in option (a) halogen (-X) is replaced by iodine.


What is ‘Electrophilic substitution’?

Electrophilic substitution reaction refers to the reaction in which an electrophile substitutes another electrophile in an organic compound.


What is the ‘Sandmeyer’s reaction’?

The Sandmeyer reaction is a versatile synthetic tool by which an amino group on an aromatic ring is replaced with a wide range of substituents by converting an amino group attached to an aromatic ring into a diazonium salt.
