From the given greenhouse gases, the most effective greenhouse gas has to be identified. Concept Introduction: Greenhouse gas: Earth receives solar energy from sun, which is in range of wavelength between 100 and 5000nm but only most radiations are in 400-700nm (visible region). On the other hand, earth surface emits radiation of wavelength greater than 4000nm (IR region). These outgoing IR radiations are only absorbed by IR active compounds. Compounds having dipole moment or its vibrational motion produce dipole moment are IR active compounds. These IR active compounds are called as greenhouse gas. Example: water and Carbon dioxide.
