Which of the following order are correct as per the properties mention

1.	Which of the following order are correct as per the properties mentioned against each ?A. `As_(2)O_(3) lt SiO_(2) lt P_(2)O_(3) lt SO_(2)` Acid strength.B. `AsH_(3) lt PH_(3) lt NH_(3)` Enthalpy of vapourisationC. `S lt O lt Cl lt F` More negative electron gain ethalpy.D. `H_(2)O gt H_(2)S gt H_(2)Se gt H_(2)Te` Thermal stability.
Answer» Correct Answer - A::D are both correct answers. In general greater the electronegativity of the element more is the acidic strength of the oxide. Thermal stability of the hydrides of oxygen family decreases with increase in bond length.
