Question

Match the column A with column B
$\begin{array}{cc}ColumnA& ColumnB\\ \text{(i)Cathode}& \text{a.Attracts negative charges}\\ \text{(ii)Anode}& \text{b.Extraction of metals}\\ \text{(iii)Alcohol}& \text{c.Electrolyte}\\ \text{(iv)Electrometallurgy}& \text{d.Attracts positive charges}\\ & \text{e.Non electrolyte}\end{array}$

• A. (i)-a,(ii)-b,(iii)-c,(iv)-d,
• B. (i)-d,(ii)-c,(iii)-a,(iv)-b
• C. (i)-d,(ii)-a,(iii)-e,(iv)-b
• D. (i)-e,(ii)-a,(iii)-b,(iv)-c

Answer 1

The correct option is C (i)-d,(ii)-a,(iii)-e,(iv)-b

Cathode attracts the positively charged ions (cations). Hence the name cathode.
Anode attracts the negatively charged ions (anions). Hence the name anode.
Alcohol is a covalent compound and it doesn't disassociate into ions. Hence, it is a non-electrolyte.
Electrometallurgy is the process of extraction of a metal in its pure form from the compounds containing that metal.
