Which of the following statement is not true for hydrolysis of XeF6?
XeOF4 is formed.
XeO2F2 is formed.
It is a redox reaction.
XeO3 is formed
C.
It is a redox reaction.
Hydrolysis of XeF6 is not a redox reaction. XeF6 reacts violently with water, but slow hydrolysis by atmospheric moisture gives highly explosive solid, XeO3.
XeF6 (s) + 3H2O (l) XeO3 (s) + 6HF (aq)
Partial hydrolysis of XeF6 yields XeOF4 and XeO2F2.
XeF6 + H2O XeOF4 + 2HF
XeF6 +2H2O XeO2F2 + 4HF
Which of the following is not a green house gas?
Hydrogen
Carbon dioxide
Methane
Nitrous oxide or N2O
Arrange the following compounds in increasing order of reactivity towards nucleophilic addition reaction.
(I) C6H5COCH3

(III) C6H5CHO
(IV) Cl-CH2-CHO
IV > III > II > I
IV > II > III > I
I > II > III > IV
III > IV > II > I
