kamalska (mk23835) – HW00 – Quigley – (104001) 1 This print-out should have 31 questions. Multiple-choice questions may continue on the next column or page – fnd all choices beFore answering. 001 10.0 points What is the molecular geometry oF nitrous oxide (N 2 O) oF atomic order N - N - O? 1. trigonal planar 2. trigonal pyramidal 3. linear 4. bent 002 10.0 points What group must atom A come From in the Lewis dot structure For CH 2 A? The central atom is carbon, which is bonded to two hy- drogen atoms and double-bonded to A. Both carbon and A Follow the octet rule. 1. VA 2. VIIIA 3. IIA 4. IA 5. VIIA 6. VIA 7. IVA 8. IIIA 003 10.0 points Antibonding orbitals 1. are responsible For dipole moments in molecules. 2. are higher in energy than bonding orbitals and are thereFore populated with electrons prior to bonding orbitals. 3. lend instability to a molecule when popu- lated with electrons. 4. are responsible For high ionization ener- gies in atoms. 5. are lower in energy than bonding orbitals and are thereFore populated with electrons prior to bonding orbitals. 004 10.0 points The phosphorous anion (P ) has how many total electrons and how many valence elec- trons? 1. 15; 4 2. 16; 4 3. 14; 6 4. 14; 5 5. 16; 5 6. 16; 6 7. 15; 5 8. 14; 4 9. 15; 6 005 10.0 points A molecule AB 3 has eight shared electrons and Follows the normal octet rule. Pick the true statement. 1. It exhibits resonance. 2. It must be an anion. 3. It is sp 3 hybridized. 4. It has an angular geometry.
