I want to ask what is the relation between "electronegativity(EN)", "polarizability", "polarizable" ? are the applications of these terms restrict solely to covalent bonds or solely to ionic bond? or is it just free for us to apply them to whatever kind of bond?
besides, in the comparison between CBr4 and CCl4's boiling point, why don't we refer to the difference in EN but say that Br is more polarizable so it has a stonger intermolecular force and higher b.p.?
in case of comparing HBr, HCl's boiling point, what should we use to explain? EN or "more polarizable" or something else?
thanks for your help. exam ahead.
