Which of the following is not favourable for the proper dehydration of...
Secondary and tertiary alcohols give alkenes as major products during dehydration, because elimination competes over substitution. Hence, this method is mainly used for primary alcohols.

Which of the following is not favourable for the proper dehydration of...
Presence of bulky alkyl groups in the alcohol
Alkyl groups are known to stabilize the intermediate carbocation formed during the dehydration of alcohol to form ether. However, the presence of bulky alkyl groups can hinder the proper dehydration process for the following reasons:
1. Steric hindrance:
Bulky alkyl groups can create steric hindrance, making it difficult for the alcohol molecules to approach each other and undergo dehydration. This can slow down the reaction or even prevent it from occurring efficiently.
2. Hindered access to the reaction site:
The bulky alkyl groups can also hinder access to the reaction site, preventing the necessary interactions between the alcohol molecules and the dehydrating agent. This can result in a lower yield of the desired ether product.
3. Slower reaction rate:
Due to the steric hindrance and hindered access, the presence of bulky alkyl groups can lead to a slower reaction rate. This can prolong the reaction time required for the formation of ethers, making the process less efficient.
In conclusion, the presence of bulky alkyl groups in the alcohol is not favorable for the proper dehydration of alcohol to form ether due to steric hindrance, hindered access to the reaction site, and slower reaction rate.
