The species that does not contain peroxide ions is:
(a) PbO2 does not contain -O-O- bond. It is lead dioxide.
The formation of is difficult compared to because
+H+
According to Drago's rule lone pair on phosphorous resides in almost pure s- orbital, hence due to non directional nature, its overlapping tendency is greatly reduced in comparison to a lone pair present in hybrid orbital, which is directional as present in
Concentrated nitric acid reacts with iodine to give:
I2 + 10HNO3 2HIO3 + 10NO2 + 4H20
Partial Hydrolysis of one mole of peroxodi-sulphuric acid produces:
Which of the following is the correct statement?
-Bond dissociation energy of F2 is less than that of Cl2
-Cl has higher E.A. than fluorine
-HF is weaker acid than HCl, due to higher bond energy
Incorrectly matched characteristic is:
Among the following compounds, which on heating do not produce N2?
(c) NH4Cl+ NaNO2→NH4NO2+NaCl
NH4NO2 N2↑ +2H2O
Ba(N3)2 →Ba+3N2↓
2NH4Cl+CaO→CaCl2+2NH3↑+H2O)
Which of the following oxyacid contains both P-H and P-P bond simultaneously?
In which process does the nitrogen undergo oxidation?
B(OH)3 + NaOH NaBO2 + Na[B(OH)4] +H2O
How can this reaction is made to proceed in forward direction?
(a) H3BO3 acts as weak monobasic Lewis acid.
(i) B(OH)3 + NaOH Na[B(OH)4]
on addition of cis 1,2 diol in H3bo3 solution, acidic strength of H3BO3 increases due to chelation effect.
Which of the following has been arranged in order of decreasing bond dissociation energy:
Bond dissociation energy
Order of bond length: P-O > S-O >Cl- O Order of BDE: Cl-O> S-O>P-O
NO2 is the anhydride of
When PCl3 is hydrolysed then oxyacid of phosphrous is obtained.The basicity of oxyacid is
Which set of oxide of nitrogen is paramagnetic in nature?
NO and NO2 are paramagnetic in nature
S-S bond is present in
