|
|
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: -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-2: -A molecule that is slightly positive on one end and slightly negative on the opposite end is a polar molecule. Polar molecules are the result of polar bonds and asymmetry in molecular geometry. Polar bonds result when electrons are not shared equally between the two bonded atoms.
Detailed explanation-3: -Because water is polar, with slight positive and negative charges, ionic compounds and polar molecules can readily dissolve in it.
