Explain the following: a)PC15 is known but NClg is not known.b)H20 is liquid but H2S is gas.answer plz |

Answer» forms five bonds by using the d-orbitals to "expand the octet" and have more places to put bonding pairs of electrons.NCl 5 does not EXIST because there are no d-orbitals in the second energy level. THEREFORE there is no way to arrange five pairs of bonding electrons around a nitrogen atom. H2O is liquid because of its ability to form hydrogen bonds which is possible only in case of F , O and N because of their high ELECTRONEGATIVITY. While in case of H2S there is no hydrogen BOND formation . HENCE H20 is liquid while H2S is gas . |
