A question based on chemical bonding, which is to be accomplished.Answer for first question Intermolecular forces are weaker than intramolecular forces (covalent bonding). Its evidence is as available in the previous paragraph, energy required to break intramolecular force is 192.9 kJ while the energy required to break the intermolecular forces is 30.9 kJ. Since, more amount of energy is required to break, the intramolecular force is stronger than intermolecular force. Covalent bond strength > intermolecular forces Answer for second question When a substance like Br2(l) is vaporized, the change of phase is as follows, Br2(l) ⇒ Br2(g) So, the molecular form of reactant Br2 is retained in the product as well. Hence, there is no possibility for the breaking of intramolecular forces (Covalent bond). So, only intermolecular force that retains liquid state is broken to form respective gas state.
