Detailed explanation-1: -In the water molecule, there are four electron pairs. Two of them are bonded and two of them are lone pairs. This causes the water molecule to have a tetrahedral shape (it is important to note that it is a bent tetrahedral shape due to the two lone pairs).
Detailed explanation-2: -In agreement with our analysis using the Lewis formalism, water’s shape is angular, or bent, with an H-O-H bond angle of 104.5°. This is consistent with a roughly tetrahedral orientation of four electron domains about the central oxygen, two bonding pairs and two non-bonding “lone pairs".
Detailed explanation-3: -Water molecule has bent or angular shape. The O atom is sp3 hybridised with two lone pairs and two bond pairs of electrons.
Detailed explanation-4: -H2O: Water has four electron groups so it falls under tetrahedral for the electron-group geometry. The four electron groups are the 2 single bonds to Hydrogen and the 2 lone pairs of Oxygen. Since water has two lone pairs it’s molecular shape is bent.
