Important Reactions used for Organic Chemistry Conversions

In CBSE board exam, usually word problems (conversions) covering

“Properties and reactions of functional groups” carry a weightage of 5 marks.

So, it is important that this particular type of questions is not left out while

preparing for the exam.

Usually, students are confused about how to solve questions based on

organic conversions.

Here, below given are the conversions in small logical chunks which are easy

to remember.

Broadly you can classify conversions into two types – aliphatic and aromatic.

1. Aliphatic conversions:

a. For stepping up the series:

Stepping up the series means that the product has one carbon more than

that of reactant. For such a kind of conversion, convert the given compound

to an alkyl halide and then to a cyanide and then to the required organic

compound as asked in the question. This way, the product has one carbon

more than the reactant.
