CO_(2), CH_(4), N_(2) O and CFC are green house gases, because they can

CO_(2) is called a green house gas because

Assertion : Contribuition of CO_(2), CH_(4), CFCs " and " N_(2)O towards greenhouse effect is respectively 60%, 6 %, 14 % and 20 %. Reason : Greenhouse gases are radioactively active gases which prevent the short wavelength radiations emitted by earth to escape into space.

Besides CO_(2), CH_(4),CFC's and ............can also cause greenhouse effect.

CH_(3)-CH_(2)=N=O and CH_(3)-CH=N-OH are:

For real gases, van der Waals' equation is written as (P+(an^(2))/(V^(2))) (V-nb)= nRT where a and b are van der Waals' constants. Two sets of gases are: (I) O_(2), CO_(2), H_(2) and He(II) CH_(4), O_(2) and O_(2) and H_(2) The gases given in set I in increasing order of b and gases given in set II in decreasing order of a are arranged below. Select the correct order from the following:
