All of these

Solution
Question 5
1 / -0

Product $$(Y)$$ of this reaction is:

A

B

C

D

Solution

It is electrophilic aromatic substitution.
Answer is option $$B$$.
Question 6
1 / -0

Major product $$(B)$$ of this reaction is:

A

B

C

D

Solution

Fenton's regent is a solution of hydrogen peroxide with ferons ion as a catalyst that is used to oxidize contaminates or waste water.
Fenton's reagent can be used to destroy organic compounds such as tri chloroethylene $$(TLE)$$ and trichloroethylene.
Oxidation of an organic compound by fenton's reagent is rapid & exothermic & results in the oxidation of contaminate to primary carbon dioxide and water.
Question 7
