Explanation
Water - H2O
This compound has 4 electron groups so it falls under tetrahedral for the electron group geometry.
The 4 electrons are the 2 single bonds to H (hydrogen) and the 2 lone pairs of O (oxygen).
Since H2O has 2 lone pairs => its molecular shape is bent. (according to VSEPR theory, the electrons want to minimize repulsion, therefore, the lone pairs are adjacent to each other)
