Question

A water molecule is composed of two hydrogen atoms and one oxygen atom arranged in a bent shape. Since oxygen is significantly more electronegative than hydrogen, oxygen atoms have a much stronger attraction to shared electrons than does hydrogen. This unequal sharing of electrons and bent shape results in water being called a _________________ .
A)
polar molecule



B)
magnetic molecule



C)
ionic molecule



D)
covalent molecule

Answer 1

Answer: A)  polar molecule  

Explanation: Polar molecules are molecules which contain atoms of different electronegativities.

Non polar molecules are molecules which contains atoms of same electronegativities.

Water is a polar covalent molecule formed by unequal sharing of electrons. Oxygen being more electronegative tend to keep the electron pair towards itself thus generating a partial negative charge. The hydrogen acquire a partial positive charge thus resulting in a polar molecule.

The bent shape is due to repulsion between lone pairs and bond pairs of electrons.

Answer 2

I can be wrong, but I think the answer is: This unequal sharing of electrons and bent shape results in water being called a A) polar molecule.
