Ques. 1AIPMT 2015 (Cancelled)

Nitrogen dioxide and sulphur dioxide have some properties in common. Which property is shown by one of these compounds, but not by the other?

  1. Is soluble in water.
  2. Is used as a food preservative.
  3. Forms 'acid-rain'.
  4. Is a reducing agent.

Answer

(2) Is used as a food preservative.

Solution

Both NO2 and SO2 are acidic oxides, soluble in water:

2NO2 + H2O HNO3 + HNO2; SO2 + H2O H2SO3

⇒ both form acid rain.

Both can act as reducing agents (N in NO2 is +4 and can go to +5; S in SO2 is +4 and can go to +6).

As per NCERT, SO2 is used as an anti-chlor, disinfectant and preservative; NO2 is not used as a food preservative.

Answer: (2)

Ques. 3NEET 2013

Which is the strongest acid in the following?

  1. HClO4
  2. H2SO3
  3. H2SO4
  4. HClO3
Ques. 4NEET 2013

Roasting of sulphides gives the gas X as a byproduct. This is a colourless gas with choking smell of burnt sulphur and causes great damage to respiratory organs as a result of acid rain. Its aqueous solution is acidic, acts as a reducing agent and its acid has never been isolated. The gas X is

  1. CO2
  2. SO3
  3. H2S
  4. SO2

Ques. 6AIPMT 2012 (Mains)

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

  1. HF < HCl < HBr < HI : increasing acidic strength
  2. H2O < H2S < H2Se < H2Te : increasing pKa values
  3. NH3 < PH3 < AsH3 < SbH3 : increasing acidic character
  4. CO2 < SiO2 < SnO2 < PbO2 : increasing oxidising power
