Predict the order of polarity of the five different benzene derivatives, (benzoic acid, salicylic acid, p-hydroxy benzoic acid, acetanilide, and p-amino phenol) from the least to the most polar. Indicate why you think the order is so. The melting point of phenol is 40.5 degree C and that of toluene is -95 degree C. Cl+Cl → Cl2 Cl + Cl → Cl 2. The total number of electrons around each individual atom consists of six nonbonding electrons and two shared (i.e., bonding) electrons for eight total electrons, matching the number of valence electrons in the noble gas argon. Since the bonding atoms are identical, Cl 2 also features a pure covalent bond.
