Chlorobenzene is prepared commercially by
The Raschig process is a chemical process for the production of hydroxylamine, developed by German chemist Friedrich Raschig. The main step in this process, patented by Raschig in 1887, is the reduction of nitrite with bisulfite towards hydroxylamine disulfonate, which is hydrolysed to hydroxylammonium sulfate.

What is the order of reactivity of following halogen acids on alcohols?
HI, HBr, HCl
Which of the following is formed by Swarts Reaction?
On reacting ethene with HCl we get:
hydrogen chloride adds to ethene to make chloroethane:
CH2=CH2 + HCl → CH3CH2Cl
Which of the following is formed in reaction mechanism of halogenation of alkanes in presence of UV light?
Halogenation of alkanes in presence of UV light follows the free radical mechanis
Which of the following is intermediate in Sandmeyer’s reaction?
Which of the following is the major product of following reaction?
CH3CH = CH2 + HBr in the presence of peroxide gives:
Correct Answer : c
Explanation : The double bond is broken and hydrogen and bromine are added to the given compound.
Bromine will add up on secondary carbon. (Markovnikov's Rule)
CH3CH=CH2 + HBr → CH3CH(Br)−CH3(1 – bromopropane)
