1. For each compound, draw the Lewis dot structure, the number of lone pairs, and the number of electronic groups for the central atom. Each Lewis dot structure follows the octet rule: hydrogen has one bond, all other atoms are surrounded by a total of eight electrons. Each covalent bond counts as we clectrons. Each nonbonded pair of electrons (lone pairs) count as two electrons. The number of nonbonded electrons is how many electrons from the central atom are not...

Select all the statements that correctly explain why lone pairs prefer to occupy equatorial positions in a system with five electron domains. Check all that apply. A larger bond angle leads to more electron repulsion. Alone pair in an axial position will be too far away from the other electron pairs. There is less repulsion between electron domains in equatorial positions. Alone pair in an equatorial position has more space. Do you know the answer? Match each molecular geometry correctly...

Which of the following concerning electron pair space requirements and bond angles is/are incorrect? 1. Lone pairs of electrons require more space than bonding pairs. 2. Multiple bonds require the same amount of space as single bonds. 3. The HOH bond angle in H2O and the HNH bond angle in NH3 are identical because the electron arrangements (tetrahedral) are identical. Select one: a. 1 only b. 2 only c. 3 only d. 2 and 3 e. 1, 2, and 3
