How many hydrogen do you have to replace to get each of these products from 1-chlorbutane

products are :
1,1-dichlorobutane
1,2-dichlorobutane
1,3-dichlorobutane
1,4-dichlorobutane

IT is easy. What is your thinking on it?

1,2-dichlorobutane

To determine how many hydrogens need to be replaced in 1-chlorobutane to obtain 1,2-dichlorobutane, we need to analyze the structural formula of both compounds.

Let's start with 1-chlorobutane, which is composed of a butane chain (four carbon atoms) with a chlorine atom attached to one of the carbons. The structural formula can be represented as follows:

CH3-CH2-CH2-CH2-Cl

Now, let's examine 1,2-dichlorobutane. In this compound, there are two chlorine atoms attached to the first and second carbon atoms of the butane chain. The structural formula is as follows:

CH3-CH(Cl)-CH2-CH2-Cl

To obtain 1,2-dichlorobutane from 1-chlorobutane, we replace one hydrogen atom attached to the second carbon with a chlorine atom. Therefore, there is only one hydrogen substitution required to obtain 1,2-dichlorobutane from 1-chlorobutane.

I hope this explanation helps you understand the process. If you have any further questions, feel free to ask!
