• A. (i)$H_{2}O$, (ii)oil of vitriol, (iii)Contact, (iv)oxidising, (v)dibasic
• B. (i)$O_2$, (ii)oil of vitriol, (iii)Oleum, (iv)dehydrating, (v)monobasic
• C. (i)$H_{2}O$, (ii)oil of wintergreen, (iii)Solvay, (iv)dehydrating, (v)dibasic
• D. (i)S$O_2$, (ii)oil of winter green, (iii)Contact, (iv)oxidising, (v)monobasic

Answer 1

The correct option is A (i)$H_{2}O$, (ii)oil of vitriol, (iii)Contact, (iv)oxidising, (v)dibasic

Conc. $H_{2}S{O}_4$ chars paper, wood, and sugar by removing water from them. It is also known as oil of vitriol. It is manufactured by Contact process. It is a strong oxidising agent and dibasic acid.

So the correct match is (i)$H_{2}O$, (ii)oil of vitriol, (iii)Contact, (iv)oxidising, (v)dibasic.

Hence option A is correct.
