Answer 1

The correct option is A (1) $\to$ (c), (2) $\to$ (a), (3) $\to$ (b), (4) $\to$ (d)

Bleaching powder $⟶$ Calcium oxychloride $Ca(OCl{)}_2$

Baking soda $⟶$ Sodium bicarbonate $NaHC{O}_3$

Washing soda $⟶$ Sodium carbonate $N{a}_{2}C{O}_3$

Plaster of Paris $⟶$ Calcium sulphate hemihydrate $CaS{O}_4\cdot 2H_{2}O$
