Nitrobenzene is formed as the major product along with a minor product in the reaction of benzene with a hot mixture of nitric acid and sulphuric acid. The minor product consists of carbon `42.86%`, hydrogen `2.40%`, nitrogen `16.67%` and oxygen `38.07%`.
a. Calculate the empirical formula of the minor product.

Text Solution

Verified by Experts

The correct Answer is:
`C_(6)H_(4)N_(2)O_(4)`


Empirical formula of minor product =`C_(3)H_(2)NO_(2)`
Empirical formula weight =`84`
or `1.84 =2.53 xx5.5/(Mw)xx1/45xx1000`
or ` Mw=168`
`"Molecular weight"/"Empirical formula weight" =168/84=2`
Molecular formula of minor product =`2xxC_(3)H_(2)NO_(2)=C_(6)H_(4)N_(2)O_(4)`

Vladimir Markovnikov rule : Alkenes undergo electrophilic addition reactions. It is triggered by the acid acting as a electrophile toward t-electrons of the double bond. Markovnikov's rule states that when an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen atom adds to the carbon that has the greater number of hydrogen, e.g., Identify the major products r_1, r_2, and r_3 in the given reactions.
