The oxygen end is slightly negative and the hydrogen end is slightly positive
|
|
|
The hydrogen end is slightly negative and the oxygen end is slightly positive
|
|
|
The hydrogen and oxygen ends change in polarity
|
|
|
Because it is hydrophobic
|
Detailed explanation-1: -Polarity: Although the net charge of a water molecule is zero, water is polar because of its shape. The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules.
Detailed explanation-2: -While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen.
Detailed explanation-3: -As a result, the water molecule is “polar”, meaning the molecule has an unequal distribution of charge. The oxygen atom pulls the electrons away from the hydrogen atoms resulting in the oxygen atom having a partial negative charge (-
