Iodine on reaction with concentrated nitric acid forms:
1. HOI
2. HI
3. HIO3
4. HIO4
Among the following reactions, N2 is not generated by heating:
1. (NH4)2Cr2O7
2. NH4Cl + NaNO2
3. NH4Cl + CaO
4. Ba(N3)2
Oxidation of nitrogen among the following reactions is indicated by -
1. \(\mathrm{N}_2 \rightarrow 2 \mathrm{NH}_3
\)
2. \(\mathrm{N}_2 \mathrm{O}_4 \rightarrow 2 \mathrm{NO}_2
\)
3. \(\mathrm{NO}_3{ }^{-} \rightarrow \mathrm{N}_2 \mathrm{O}_5
\)
4. \(\mathrm{NO}_2^{-} \rightarrow \mathrm{NO}_3^{-}\)
\(\mathrm{PCl}_3\) upon hydrolysis gives an oxyacid of phosphorous.
The basicity of that oxyacid is:
1. | One | 2. | Two |
3. | Three | 4. | Four |
