(1 point) hydrogen fluoride (hf) has a lower molecular weight compared to hydrogen chloride (hcl), yet its boiling temperature is much higher. choose the best explanation for this phenomenon: . a. the chlorine atom has a lower electronegativity than fluorine, thereby making the bond within the molecule weaker ob. the equilibrium distance between atoms within the hf molecule is smaller than that for the hci molecule c. none of these od. two types of secondary (or intermolecular) bonding are present between hydrogen fluoride molecules, whereas only one type of secondary bonding is present between hydrogen chloride molecules o e. the bond between hydrogen and chlorine has greater ionic character compared to that of hydrogen and fluorine of. none of the above
