Melting point of group 17 elements
WebDue to small size and high electronegativity of elements, hydrides of Nitrogen (N), Oxygen (O) and Fluroine (F) have the ability to form extensive intermolecular (i.e between 2 molecules) hydrogen bonding. Thus, a large amount of energy is required to break these bonds, i.e., the melting and boiling points of hydrides of these elements are abnormally … Web(b) Elements of group 17, in decreasing order of reactivity.
