Embibe Experts Solutions for Chapter: The p-Block Elements, Exercise 1: AIPMT - 25th July 2015

Given below are two statements:

Statement I: The boiling points of the following hydrides of group $16$ elements increases in the order - ${\mathrm{H}}_2\mathrm{O}<{\mathrm{H}}_2\mathrm{S}<{\mathrm{H}}_2\mathrm{Se}<{\mathrm{H}}_2\mathrm{Te}$.

Statement II: The boiling points of these hydrides increase with increase in molar mass.

In the light of the above statements, choose the most appropriate answer from the options given below:

Choose the correct statement:

Noble gases are named because of their inertness towards reactivity. Identify an incorrect statement about them.

Statement I: Acid strength increases in the order given as

$\mathrm{HF}<<\mathrm{HCl}<<\mathrm{HBr}<<\mathrm{HI}$

Statement II:
As the size of the elements $\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I}$ increases down the group, the bond strength of $\mathrm{HF}, \mathrm{HCl}$ $\mathrm{HBr}$ and HI decreases and so the acid strength increases.

In the light of the above statements, choose the correct answer from the options given below.

In which one of the following arrangements the given sequence is not strictly according to the properties indicated against it?

Which of the following oxide is amphoteric in nature?

Which one of the following reactions does not come under hydrolysis type reaction?

Acidity of diprotic acids in aqueous solutions increases in the order:
