1 Explain why oxygen forms two bonds to hydrogen to make a water molecule $$\left({\mathrm{H}}_2\mathrm{O}\right)$$, while nitrogen forms three bonas to hydrogen to make a molecule of ammonia $$\left({\mathrm{NH}}_3\right)$$. The lone pairs 2 Consider the molecular formula $${\mathrm{C}}_2{\mathrm{H}}_2$$. Would you expect this compound to contain any double or triple bonds? Use your knowledge of typical bonding patterns to fully support your answer. 3 Consider the molecular formula $${\mathrm{CH}}_5\mathrm{N}$$. Would you expect this compound to contain any double or triple bonds? Use your knowledge of typical bonding patterns to fully support your answer. How many covalent bonds would you expect silicon (Si) to form? Explain your answer. Consider the molecular formula $${\mathrm{COCl}}_2$$. Based on your knowledge of bonding patterns, does it makes sense for the chlorine atoms to be bound to the carbon or to the oxygen atom? Explain your answer.
