Question

Iupac Name of CH 3- CHcl-
CH 2-CHO​

Answer 1

$\huge \fbox{ \underline \purple{Answer }}$

Given Chain :

          Cl

           |

CH₃ - CH - CH₂ - CHO

Let us note some important points which are given in this question,

✭ Halogens form in used in prefix (i.e) chloro (cl)

✭ $Aldehyde$ is the functional group then we need to add suffix as $"al"$

✭ Let us start numbering the carbon chain

✭ Always numbering should start from the functional group of carbon chain

          Cl

            |        

CH₃ - CH - CH₂ - CHO

 4        3       2         1

✧ Chlorine is present at 3rd carbon

✧ $"al"$ is the functional group

✧ There are four carbon atoms in the longest chain. The prefix of the compound will be "but"

✧ Hence the I.U.P.A.C  Name of  this compound is

$3 - chloro -Butanal$

$\underline{\underline{ \sf \huge \red{✪Extra Bytes✪}}}$

To give I.U.P.A.C name of any compound easily let us remember these common steps it will easy

✪ Identify the functional group  ✪

The compound is a hydrocarbon with single bonds between the carbon atoms.

✪ Find the longest carbon chain  ✪

Find the number of carbon atoms in the chain accordingly you can give the prefix

✪ Number the carbon atoms in the longest chain  ✪

The number of carbon is very important. Always numbering should start from functional groups .

If double or triple bonds are present then it should get lowest number accordingly

✪ Add  functional group name  ✪

We should provide the required suffix to the compound

✪ Combine the elements of the name into a single word  ✪

Add every words and numbers u used in naming process. The resultant will be your name of the I.U.P.A.C compound
