Unformatted text preview: P 2 Cl 4 at low temperature, when it adopts a trans configuration. 2. (f) explain what is meant by the identity operation of a molecule or polyatomic ion. 2. (a) Oxides are the bane of any synthetic chemist that deals with phosphorus containing speciesit is sooooo easy to form phosphine oxides. Give the VSEPR diagram of the best Lewis Structure for a molecule of trichlorophosphine oxide 7 in the box on the right. 3. (b) Illustrate the application of all different types of symmetry operations , other than the identity operation, on the VSEPR diagram you drew in 3. (a), by drawing in the required axes, planes or points and labeling them with the name of their operator. 3. (c) Use the flow diagram given below to identify the point group for a molecule of trichlorophosphine oxide in the box below.
