1.	The gas released from vehicles exhaust are1) Carbon monoxide2) Sulphur dioxide3) Oxides of nitrogenOptions:a) 1 and 2b) 1 and 3 c) 2 and 3 d) 1,2 and 3
Answer» The correct option is (d) 1, 2 and 3. • The vehicular exhausts consists of all the above mentioned gases, the only difference is the amount of these gases. • Although, majority of vehicular exhausts consists of Carbon dioxide ( because the main product of the combustion of fossil fuel is carbon dioxide and water vapour). • But there's presence of small amount of Carbon monoxide which is produced if incomplete combustion of fuel takes place. • Sulphur dioxide is produced because sulphur is an active component of lead which is added in petrol as an anti knocking agent. • Vehicular exhausts also consists of Oxides of nitrogen like Dinitrogen oxide, PAN, etc.
