Answer 2

Conversion of Butane to But-1-ene to Dichlorobutane to Butane-1,2-diol

To convert butane to but-1-ene, we can use a process called dehydrogenation. This involves removing two hydrogen atoms from butane to form a double bond between two carbon atoms. The reaction can be represented by the following chemical equation:

Butane → But-1-ene

C4H10 → C4H8

To convert but-1-ene to dichlorobutane, we can use a process called chlorination. This involves replacing one or more hydrogen atoms with chlorine atoms. In this case, we need to replace two hydrogen atoms with two chlorine atoms. The reaction can be represented by the following chemical equation:

But-1-ene → Dichlorobutane

C4H8 + Cl2 → C4H8Cl2

Finally, to convert dichlorobutane to butane-1,2-diol, we can use a process called hydrolysis. This involves breaking the carbon-chlorine bonds and replacing them with hydroxyl groups (-OH). The reaction can be represented by the following chemical equation:

Dichlorobutane → Butane-1,2-diol

C4H8Cl2 + 2H2O → C4H10O2 + 2HCl

Please note that the reactions mentioned above are simplified representations and may require specific reaction conditions and catalysts for the conversion to occur efficiently.
