Which one of the orders is correctly matched with the property mentioned against it?
Show Hint
General trends to remember:
- Boiling points of hydrides increase down a group, with exceptions for NH$_3$, H$_2$O, and HF due to H-bonding.
- Acidic character of oxides increases with the oxidation state of the central atom.
- Acidic strength of binary hydrides increases down a group in p-block (e.g., HF<HCl).
- Bond angles in similar hydrides (like H$_2$O, H$_2$S) decrease down the group as the central atom's electronegativity decreases.

- H$_2$S<H$_2$O<H$_2$Se<H$_2$Te (Boiling point)
- N$_2$O<NO<N$_2$O$_3$<N$_2$O$_4$<N$_2$O$_5$ (Acidic nature)
- HI<HCl<HBr<HF (Acidic nature)
- H$_2$O<H$_2$S<H$_2$Se<H$_2$Te (Bond angle)

Top Questions on p -Block Elements
- Statement-I: An element ‘X’ of P-block forms a hydride H–X, which has the longest bond length, then element ‘X’ will have the shortest covalent radius.
Statement-II: An element ‘E’ of Group 15 forms hydride EH$_3$, that has least B.P. The maximum covalency of E is 4.
