(i) Use valence shell electron pair repulsion theory (VSEPR) to predict the shape of the molecule comprising oxygen, nitrogen and fluorine atoms, which has the formula ONF, and where nitrogen is the central atom.
(ii) Determine the symmetry point group of ONF and give brief reasoning.
(b) Determine, with brief reasoning, the number of normal modes of vibration that the ONF molecule will have. Would you expect all the modes of vibration to be active in both the infrared and Raman spectrum? Explain your answer using the rule of mutual exclusion. (A couple of sentences)
