|
The oxygen end has a slight negative charge and the hydrogen end has a slight positive charge
|
|
|
Electrons are shared evenly between the hydrogens and the oxygen.

|
|
The charge on each end of the molecule is balanced.

Detailed explanation-1: -Answer. the option 2) is the correct answer..!! Water is a “polar” molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge ( ) near the oxygen atom due the unshared pairs of electrons, and partial positive charges ( ) near the hydrogen atoms.
Detailed explanation-2: -Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.
Detailed explanation-3: -In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
