Answer the questions in the table below about the shape of the borane (BH3) molecule.
How many electron groups are around the central boron atom?
Note: one "electron group" means one lone pair, one single bond,
one double bond, or one triple bond.
What phrase best describes the arrangement of these electron
groups around the central boron atom?

In a hydrogen molecule, the two hydrogen atoms are held together by a single bond with a bond energy of 436 kJ/mol of hydrogen. In
other words, to break the H-H bonds in one mole of molecular hydrogen requires the expenditure of 436 kJ of energy. Using the
balanced chemical equation for the formation of water from oxygen and hydrogen (shown above), and interpreting the stoichiometric
coefficients as mole amounts, how much energy must be expended in breaking the H-H bonds?
kJ
Which type of intermolecular force accounts for each of these differences? (a) CH3OH boils at 65 °C; CH3SH boils at 6 °C. (b) Xe is a liquid at atmospheric pressure and 120 K, whereas Ar is a gas under the same conditions. (c) Kr, atomic weight 84 amu, boils at 120.9 K, whereas Cl2, molecular weight about 71 amu, boils at 238 K. (d) Acetone boils at 56 °C, whereas 2-methylpropane boils at -12 °C.
