, Which of the following statements regarding
ionic interactions is true?
A. The lower the magnitude of the
charge on the ions, the stronger
the ionic interaction (more
negative bond energy)
B. The lower the dielectric constant
of the medium the interaction is
taking place in, the stronger the
ionic interaction (more negative
bond energy)
C. The larger the distance between
the ions, the stronger the ionic
interaction (more negative bond
energy)
, For a same hydrogen bond, in which environment
it is stronger (more negative):
A. In water
B. In hexane
, Breaking bonds and intermolecular
forces:
A. is always endothermic
(absorption of heat)
B. Is always exothermic
(releasing heat)
C. Is sometimes exothermic
and sometimes
endothermic, depending
upon the bond strength
