Detailed explanation-1: -A molecule is a group of atoms held together by covalent bonding that acts as an independent unit. Table sugar is a covalent compound. The chemical formula for a molecule of table sugar is C 12H22O11. One molecule contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

Detailed explanation-2: -A molecule is a neutral group of atoms joined by covalent bonds.

Detailed explanation-3: -Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.

Detailed explanation-4: -But covalent compounds have weak intermolecular forces of attraction between the shared pair of electrons. Therefore, a very small amount of energy is required to break the bonds and therefore they have low melting points. Hence, the given statement is false.
