Question 4:Name the suitable alcohol and reagent, from which 2-Chloro-2-methyl
propane can be prepared.
The correct answer is – 2-Chloro-2-methylpropane can be prepared from an alcohol and a suitable reagent using an elimination reaction.
A common method for the preparation of 2-chloro-2-methylpropane is the dehydration of 2-methyl-2-propanol using concentrated sulfuric acid as the dehydrating agent. The reaction can be written as:
2-methyl-2-propanol + H2SO4 → 2-chloro-2-methylpropane + H2O
In this reaction, concentrated sulfuric acid acts as a strong dehydrating agent, promoting the removal of water from the alcohol and forming the corresponding alkyl halide.
It is important to note that the use of concentrated sulfuric acid can be hazardous and proper precautions should be taken while handling it.
