Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water has ____ molecular shape.
A
Linear
B
Pyrimidal
C
Planar
D
Bent
Explanation: 

Detailed explanation-1: -Water is a bent-shaped molecule. One water molecule has one oxygen atom, two hydrogen atoms, and one hydrogen atom. Tetrahedral electron pair geometry gives water its curved form.

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: -If a molecule has 2 bonds and 0 lone pairs, it is linear. If a molecule has 3 bonds and 0 lone pairs, it is trigonal planar. If a molecule has 3 bonds and 1 lone pair, it is bent or angular.
