1.	Which of the following orders are correct as per the properties mentioned against ? (a) `As_(2)O_(3)ltSiO_(2)ltP_(2)O_(3)SO_(2)` Acid strength. (b) `AsH_(3)ltPH_(3)ltNH_(3)` Enthalpy of vaporisation. (c )`SltOltClltF` More negative electron gain enthalphy. (d) `H_(2)OgtH_(2)SgtH_(2)SegtH_(2)Te` Thermal stability.
Answer» Correct Answer - A::D (a) `underset("acidic strength increases")overset(As_(2)O_(3)ltSiO_(2)ltP_(2)O_(3)ltSO_(2))to` (b) Correct order is `underset("enthalphy of vaporization")overset(AsH_(3)gtPH_(3)gtNH_(3))to` (c ) `SltOltClltF` More negative electron gain enthalpy (d) `H_(2)OgtH_(2)SgtH_(2)SegtH_(2)Te` Thermal stability decreases on movind top to botten due to increase in its bond length.

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.
