Given below are two statements: Statement I: The boiling point of hydrides of Group 16 elements follow the order H₂O > H₂Te > H₂Se > H₂S. Statement II: On the basis of molecular mass, H₂O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H⁻bonding in H₂O, it has higher boiling point. In the light of the above statements, choose the correct answer from the options given below:
Among Group 16 elements, which one does NOT show –2 oxidation state?

Given below are two statements: Statement I: The boiling points of the following hydrides of group 16 elements increases in the order: H₂O < H₂S < H₂Se < H₂Te. 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.
Among the following alkaline earth metal halides, one which is covalent and soluble in organic solvents is:
Statement I : Acid strength increases in the order given as HF << HCl << HBr << HI. Statement II : As the size of the elements F, Cl, Br, I increases down the group, the bond strength of HF, HCl, 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.
