Question

Excess acid can be used to achieve maximum completion of reaction.

(a) True

(b) False

I got this question during an online exam.

This is a very interesting question from Physical and Chemical Factors topic in section Sulfonation and Sulfation of Unit Processes

Answer 1

Right choice is (a) True

The explanation is: Excess acid is also used to achieve maximum completion of reaction in the sulfation of alcohols. Thus, lauryl alcohol is reacted to the extent of 90 per cent by employing a 70 per cent excess of monohydrate acid, Oleum gives excessive decomposition.
