Water molecule has bent structure whereas carbon dioxide molecule is linear |

Answer» Solution :In `H_(2)O`, OXYGEN atom is `sp^(3)` hybridised with two lone PAIRS. The four `sp^(3) ` hybridised ORBITALS possess a tetrahedral geometry with two comers occupied by hydrogen atoms and other two by the lone pairs. The bond angle is REDUCED to `104,5^(@)` from `109.5^(@)`because of greater repulsive forces between lp - Ip and the molecule so gain V-shape or bent structure (angular structure).  In `CO_(2)` molecule, carbon atom is sp-hybridised. The two sp hybrid orbitals are ORIENTED in opposite direction forming an angle of `180^(@)`.  So `H_(2)`Omolecule has bent structure and `CO_(2)` molecule is linear. |
