Introduction of p-nitro acetanilide

Answer 1

The reaction type is EAS (Electrophilic Aromatic Substitution). When dealing with aromatic substitutions you have to take into consideration what positions the different types of substitutes prefer.

In this situation you are dealing with Nitro-groups (NO2), which are said to prefer meta.

The mechanic itself is quite simple, you have to start out by figuring out the product of the reaction between the acids, which generate the nitro-group.

What happens when you add H2SO4 and HNO3 together? (These are the most commonly used reagents in this reaction). You know that one nitro group is generated, the rest is simple. Just remember the ion from sulfur acid, this will play a key role later on.

So NO2 groups are meta-positioning, thus the double bond from the aromat will attack NO2+. After that you draw the resonance, and finish with a hydrogen being attacked by the ion from sulfuric acid, returning the double bond and giving you your product.

Answer 2

when acetone is treated with hno3 in the presence of conc h2so4 get paranitro aacetanalide

Answer 3

property of peranitroacetelide
