Question

Is use of Excessive Sulfonating agents good for industrial processes?

(a) Yes

(b) No

(c) None of the mentioned

(d) Depends on other factors

I have been asked this question during a job interview.

My question is from Chemical Structures in section Sulfonation and Sulfation of Unit Processes

Answer 1

Right answer is (a) Yes

For explanation I would say: Use of excess sulfonating agent does improve the yield and is standard laboratory and industrial practice even though complete reaction is still not achieved.
