Question

When halate is treated with fluorine, the product obtained is:
A. halide
B. perhalate
C. hypo-halite
D. all of these

Answer 1

Hint: Treatment with any of many inorganic fluorides can result in the substitution of a halogen atom in an organic compound by fluorine. Mercury, silver, antimony, and hydrogen fluoride are the most common. The latter is used wherever possible because of its low cost , ease of handling and high fluorine content.

Complete step-by-step answer:
Here we first need to know that halate is a salt of chloric, bromic or iodic acid.
Iodic acid can be isolated, but chloric and bromic acids are only found in aqueous solutions.
A salt of chloric, bromic or iodic acid reacts with Fluorine to give perhalate.
So, the correct option is B.

Note – To solve such problems we need to know the reactions. But most of the time in chemistry we need to learn the terms as it is asked directly. Learning exceptions are the best option to study smartly for competitive exams. We can recognize there is a break in every sequence in chemistry and that is where from the questions arise. Learning definitions, terms and tricks for various concepts will help you a lot in this particular subject.
