10 in a bond between an atom of carbon and an atom of fluorine, the fluorine atom has a
(1) weaker attraction for electrons
(2) stronger attraction for electrons
(3) smaller number of first-shell electrons
(4) larger number of first-shell electrons

The best answer is (2) stronger attraction for electrons, for the fluorine atom has a higher electronegativity than the carbon one, if not highest of all nonmetals.
Hope this helps~

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
