Web12 Ans: A Much lower energy is required to vaporise C to F compared to A and B. Thus A is likely to be a metal (Al) with high boiling point, B is likely to be Si (giant covalent lattice) with high boiling point too, whereas C to F are simple covalent molecules with weak intermolecular forces of attraction between molecules. A is Al. Al 2 O 3 is an amphoteric …
