The molecular structure of ethane is shown below;

1. Considering the 3D shape of the molecule and the measured electronegativities of the atoms in this molecule, is this a polaron-polar/charged molecule? Explain your answer briefly.

2. The energy required to break the C-C bond in ethane is 450 kJ/mol and the bond length is 1.5 . Assume that we can model the vibrations in this bond by the following harmonic oscillator equation;

   // $%&' = $%&'( -) where $%&' = 900 / .

   A certain amount of ethane is kept in a container at 500 K. Is the C-C bond likely to break at this temperature? Justify your answer by calculations.

3. Provide a likely percent distortion in the C-C bond one would expect to observe at this temperature. Justify your answer by calculations.
