What is the shape of H2O?
|
|
linear
|
|
|
tetrahedral
|
|
|
bent
|
|
|
trigonal pyramidal
|
Explanation:
Detailed explanation-1: -The shape of water molecule which should be tetrahedral has a bent or distorted tetrahedral shape with a bond angle 104.5o.
Detailed explanation-2: -Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°.
Detailed explanation-3: -Hence, according to VSEPR theory, the water molecule arrives at a bent or a V-shape due to the presence of lone pair-lone pair, lone pair-bond pair and bond pair-bond pair repulsions. So the answer is V-Shape.
