In CBSE Board exam, conversions usually carry a weightage of 5 Marks, so it is important that you do not miss out on these particular type of questions while preparing for your exams

So given below are a few conversions, explained in small logical steps which are easy to remember.

Basically conversions are classified up-to 2 types

(1) Aliphatic (2) Aromatic

First we will discuss about Aliphatic conversions

Aliphatic Conversions

(a) Stepping up the series:

(1) If we have to increase number of carbon atom in the series, then convert the reactant into alkyl halide and then to a cyanide, and then to the required organic compound as asked in the question. In this way we can increase the number of carbon atom in the series.


(b)  Stepping down the series

Stepping down the series means that the product has one carbon less than that of its reactant. For that convert the given compound to an amide \left( {{\rm{R}} - {\rm{CON}}{{\rm{H}}_{\rm{2}}}} \right) and then let it undergo Hoffmann Bromamide degradation reaction and you will get the desire product.




Aromatic Conversions

These are based upon general reactions of different substances.
