Water is a universal solvent and has hydrogen bonding. Polar molecules are those, which dissociate in water and releases hydrogen (H+) or hydroxyl ions (OH-).
In water molecule, the two hydrogen atoms share electrons with the more electrophilic oxygen atom. Because of the high electro negativity of oxygen, the electron pair spend most of the time towards the nucleus of the oxygen atom than the hydrogen nucleus.
Thus, in water molecule, hydrogen atoms take partial positive charge, and oxygen atom takes partial negative charge, and forms a polar covalent bond. Hence, water is a polar molecule.
Because of the presence of polar covalent bonds in water, water works as a good solvent. Molecules which are miscible and soluble in water are called as “hydrophilic (water loving) molecules.” Most of the polar and ionised molecules are hydrophilic in nature.
Cohesive property of water molecules is the ability of water molecules to cling to each other by means of hydrogen bonding. This property enables the water to exist in liquid state under normal conditions of temperature, and pressure. Water has a high specific heat value and it is a versatile solvent due to its polarity.
The adhesive property of water is the ability of water molecules to get attached to other polar surfaces.
Thus, the options (d), is incorrect.
Therefore, the correct option is –
a. Water has a relatively high specific heat value,
b. water has strong cohesive and adhesive properties,
c. polarity of water allows it to act as a versatile solvent
