(b) How would you strength account for the following situations?
(i) The acidic strengths of these compound increase in the following order:
`PH_(3)ltH_(2)SltHCI`
(ii)The oxidisting power of oxoacids of chlorine follows the order :
`HCIO_(4)ltHCIO_(3)ltHCIO_(2)ltHCIO`
(iii) In vapour state sulphur exhibits paramagnetic behaviou.

Explanation

To address the question, we will break down each part and provide a detailed explanation for the observed phenomena.

### (i) The acidic strengths of these compounds increase in the following order: PH₃ < H₂S < HCl

**Step 1: Understanding Acidic Strength**
- Acidic strength refers to the ability of a compound to donate protons (H⁺ ions). The stronger the acid, the more readily it donates protons.

**Step 2: Analyzing the Compounds**
