Answer #1

Covalent bond is the strongest bond of all. It is a form of interaction in which overlapping of orbitals takes place and there is sharing of electrons.

Strength of a bond is measured as an amount of energy needed to break that bond. In covalent bonding there are two electrons are involved in just one bond formation while usually in Dipole-Dipole interaction there is only one electron is there. So for separating 2 electrons from the electrostatic influence of nucleus of the atoms more energy is needed then as compared to removing one electrons.

    2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
