Draw Lewis dot structures for each of the following.Choose the correct Lewis dot structure and VSEPR geometry of each molecule:.Calculate the formal charges on the atoms in each and use the results to choose the resonance structure that is lowest in energy: Six Lewis dot structures can be constructed using one O atom, one F atom, and one N atom.Use the molecules below to find the formal charges of the specified atoms.Then decide what the is the appropriate geometry:īased on the following Lewis dot structures, which molecule exhibits resonance?īased on the Lewis dot structures of the following organic molecules, choose the appropriate geometry. The HF, HF+MP2, CISD, and DFT (MPW1PW91) level of calculations for the total energy and the equilibrium geometry of O3 molecule have been performed using the. Pick the correct Lewis dot structure for the following molecules:ĭraw Lewis dot stuctures for each of the following. Polar covalent bonds are formed by atoms which have:Ĭhoose the most appropriate bond angles for the stated molecular geometry:Ĭhoose the number of lone pairs located on the central atom for each of the stated molecular geometries: Order the bond-types in order of their relative strengths from weakest to strongest.Ĭovalent bonds are formed by atoms which are:Ĭhoose the type of bonding that each of the following compounds or molecules employs: Single bonds repel more than double bondsĭouble bonds repel more than single bonds In VSEPR theory, which of the following is a true statement? However, in order to focus on one aspect of ozones structure, we will use a hybrid approximation. Correct answers MUST be within ± 1 unit of the third significant figure or they are scored as wrong. Ozone is a fairly simple molecule, with only three atoms. Answer all non-integer questions to at least 3 significant figures. Do NOT use commas or scientific notation when entering large numbers. If you are stumped, answers to numeric problems can be found by clicking on "Show Solution" to the right of the question.ĭo NOT type units into the answer boxes, type only the numeric values. If you wish, you may return to the test and attempt to improve your score. A new page will appear showing your correct and incorrect responses. When you have completed every question that you desire, click the " MARK TEST" button after the last exercise. Questions left blank are not counted against you. ![]() Geometry and Energy of Ethylene Glycol (tGg)31 7 10 9 2. Answer the following to the best of your ability.
