Question 1

Choose the INCORRECT statement.
◦ Molecules with all paired electrons are diamagnetic.
◦ Highly reactive molecular fragments with unpaired electrons are free radicals.
◦ An expanded octet has larger electron clouds.
◦ Electron pairs repel each other.
◦ VSEPR stands for valence-shell electron pair repulsion.

Question 2

Compound EX₄ reacts with Y₂ giving two products: EX₃Y and XY. Calculate the E-X bond enthalpy if the reaction liberates 243.6 kJ/mol and other bond enthalpies are: Y-Y 109 kJ/mol, X-Y 123.1 kJ/mol and E-Y 290 kJ/mol.
◦ 60.5 kJ/mol
◦ 547.7 kJ/mol
◦ 20.6 kJ/mol
◦ 234.7 kJ/mol
◦ 176.9 kJ/mol
