Multiple Choice QuestionsWhich of the following compounds will the significant amount of meta product during mono-nitration reaction?
C.
(a) Nitration reactions take place in presence of concentrated HNO3+ concentrated H2SO4.
(b) Aniline acts as a base. In presence of H2SO4, its protonation takes place and anilinium ion is formed
(c)Anilinium ion is a strongly deactivating group and meta directing in nature so it gives meta nitration product in a significant amount.
