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
Which of the following is not a green house gas?
Hydrogen
Carbon dioxide
Methane
Nitrous oxide or N2O
A.
Hydrogen
Greenhouse gas is a gas that contributes to the greenhouse effect by absorbing infrared radiation. It includes carbondioxide, methane, water vapour, nitrous oxide, chloroflurocarbons and ozone. Therefore, among all the options given hydrogen is not a greenhouse gas.
Arrange the following compounds in increasing order of reactivity towards nucleophilic addition reaction.
(I) C6H5COCH3
(II) CH3CO-C2H5
(III) C6H5CHO
(IV) Cl-CH2-CHO
IV > III > II > I
IV > II > III > I
I > II > III > IV
III > IV > II > I
