Match List I with List II

List I Pollutant		List II Disease / sickness
A.	Benzenesulphonyl chloride	I.	Test for primary aminies
B.	Hoffmann bromamide reaction	II.	Anti saytzeff
C.	Carbylamine reaction	III.	Hinsberg reagent
D.	Hoffman orientation	IV.	Known reaction of isocyanates

Choose the correct answer from the options given below ;

Correct Option - 3


Detailed Solution:

Intermediate : R – N = C = O (Isocyanate)

(C) Carbylamine reaction ->Test for primary amine.

  $R-N{H}_{2}orAr-N{H}_2+CHC{l}_3+3KOH\to R-NCorAr-NC+3KCl+3H_{2}O$                    

(D) Hoffmann orientation -> Anti saytzeff (Formation of less substituted alkene as major product)
