A(A) $$\rightarrow$$ (iv), (B) $$\rightarrow$$ (iii), (C) $$\rightarrow$$ (i), (D) $$\rightarrow$$ (ii)
Correct Answer
B(A) $$\rightarrow$$ (iii), (B) $$\rightarrow$$ (iv), (C) $$\rightarrow$$ (i), (D) $$\rightarrow$$ (ii)
C(A) $$\rightarrow$$ (iv), (B) $$\rightarrow$$ (i), (C) $$\rightarrow$$ (ii), (D) $$\rightarrow$$ (iii)
D(A) $$\rightarrow$$ (ii), (B) $$\rightarrow$$ (i), (C) $$\rightarrow$$ (iii), (D) $$\rightarrow$$ (iv)

Solution

$$H_2SO_4$$ is used in storage batteries. $$CCl_3NO_2$$ is chloropicrrin which is known as tear gas. $$Cl$$ is the element of highest electron gain enthalpy. Sulfur is the element belongs to 16th group which are also called as Chalcogens. So the given data matches with option A. Hence option A is correct.
