Converting one organic compound to another organic compound using one or more other organic compounds or reagents by a single or multiple steps is called organic conversion.
Organic chemistry conversions of class 12 are major problems you have to do in school examinations.
Organic conversions questions have important role in organic chemistry questions. If you practise these organic conversions properly, you can get full marks for these questions in your organic conversion class 12 examinations.
You can check your knowledge about organic compounds and their reactions from organic conversions exercises. Also organic conversions will help you to get remembered those organic compounds and their reactions again again again.
In this tutorial, we discuss about

Here, we have listed a lot of exercises for you. Try to do them yourself. Then check answers and learn reactions of different organic compounds.
Organic conversions are easy if you are well aware about organic compounds and their reactions. To do a organic conversion, we have to choose what type of compounds are required in each step. Most of times we start to think from backward ( product ) to front ( initial reactant ).
As an example, we need to prepare butanal from ethanol. We start to think from butanal. First we think, what are the ways of butanal can be prepared and we select one of it. Then we rethink, what are the ways of that compound can be prepared. We repeat this process until we come to ethanol. This method should be practised very much.
Follow below guidelines to do these problems successfully.
Lets take an example. You have to prepare an ester from ethanol. You should start to think about followings.
Organic chemistry conversion example 1
In this example, our target is preparing 2-bromopropane from propanone. First thing we have to do is, identifying the our starting compound (propanol) and final product (2-bromopropane).
Preparing 2-bromopropane from propanol only takes two steps.
Then, we have to choose correct reagents for each step.
Organic conversion example 2
First, we should identify what is the our product. Phenyl phenylmethanoate is an ester compound.
Method 1, reaction of carboxylic acid halide and alcohols is the best way to prepare esters.
Therefore we have to synthesis an alcohol and a carboxylic acid chloride from given amide.
Hydrolysis of amide can be done by two ways.
In this example we choose conc. NaOH to hydrolysis of amide.
