(B) Colourless, odourless gas, inert in nature, and dilutes the activity of active component of air
Colourless gas and forms acidic and basic compounds with non-metals and metals, respectively
(D) Colourless gas, inert in nature, and present in trace amounts
(E) Gaseous form, present in variable amounts, and chemically active along with the active component of air

Options

A. BCDAE
B. DAECB
C. BCADE
D. DEABC

Answer

A

Explanation

The order of the properties of the components of air, nitrogen, oxygen, helium, carbon dioxide and water vapour, in the order of their percentages by volumes iS
(A) Colourless, odourless gas, acidic in nature, and neither combustible nor a supporter of combustion (Carbon dioxide)
(B) Colourless, odourless gas, inert in nature, and dilutes the activity of active component of air (Nitrogen)
(C) Colourless, odourless gas, and forms acidic and basic compounds with non-metals and metals, respectively (Oxygen)
(D) Colourless gas, inert in nature, present in trace amounts (Helium)
(E) Gaseous form, present in variable amounts, and chemically active along with the active component of air (Water vapour)
Hence, the correct option is (a)
