Detailed explanation-1: -Explanation: Water (H2O) is a polar molecule because the electrons of the hydrogen atoms get “pulled” towards the electrons of the oxygen atom. This makes a region of positive charge on the hydrogen atoms and the negative charge on the other end of the molecule, which is the oxygen atom.

Detailed explanation-2: -Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure.

Detailed explanation-3: -Polar molecules result from differences in the electronegativity of the atoms in the molecule. Dipoles that are directly opposite one another cancel each other out.

Detailed explanation-4: -Answer and Explanation: Water is the most polar molecule among the given molecules. This is because of the high electronegativity difference between the atoms of water (hydrogen and oxygen) and their hydrogen bonding.

Detailed explanation-5: -Water (H2O) is a polar molecule. Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule. Ammonia (NH3) is polar. Sulfur dioxide (SO2) is polar. Hydrogen sulfide (H2S) is polar. 20-Jan-2020
