Which of the following statement is incorrect?

Options

A. The zone reflining process for parification of metal is based on the difference in solubitities of the impparties in the moles and solid state of the metal
B. Utrapure sillicon, used to make semiconductores , is obtained by the zone - refkling process
C. The van Arkel method for purication of metals levolves the consversion of the metal into a hnotivoltiel stable compound
D. The dissillation process (under reduced presure)is used for the partication of `Hg`

Answer

c

Explanation

Van arkel is very useful for preparinhg after pure metals by removing all the oxegen present in the form imparity in cartain such as `2r` and `Ti` which are used in space techology
In this method .The covalent coltile stable `ZH_(2) ` then foirmed is separtial and is then decomproce by heading over a `W` filtamen at `2873 K` is given pure Ze
