Question

a) Arrange the following compounds in the order of increasing boiling points:

Ethanol, Propan-1-ol, Butan-1 -01, Butan-2-ol

b) In the lab students were asked to carry out the reaction between phenol arid conc. HNO₃. But one student, ‘A’ carried out the reaction between phenol and dil. HNO₃. Do you think that the student ‘A’ got the same result as others. Substantiate with suitable explanations. (Also write the chemical equations wherever necessary.)

Answer 1

a) Ethanol < Propan-1-ol < Butan-2-ol < Butan-1-ol

b) Student ‘A’ will get a mixture of o-Nitropehnol and p-Nitrophenol.

Other students will get 2,4,6-tnnirophenol (picncacid) as the product.
