Unformatted text preview: Guerra, Thomas – Homework 7 – Due: Oct 16 2007, midnight – Inst: Vandenbout 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. The due time is Central time. Here are more questions finishing up Chap- ter 14. Remember, the HWS could be over- loaded when the actual due time arrives Tues- day night. Room Assignments for EXAM 2 A-K WEL 1.316 L-O WEL 2.122 P-Z WEL 1.308 001 (part 1 of 1) 10 points sp 2 hybrid orbitals have 1. trigonal pyramidal symmetry. 2. tetrahedral symmetry. 3. trigonal planar symmetry. 4. trigonal bipyramidal symmetry. 5. linear symmetry. 002 (part 1 of 1) 10 points In the molecule, C 2 H 4 , what are the atomic orbitals that participate in forming the sigma bond between the C and H atoms? 1. H: 1 s and C: sp 2. H: 1 s and C: sp 2 3. H: 2 p and C: sp 3 4. H: 1 s and C: 2 p 5. H: sp 2 and C: sp 2 003 (part 1 of 1) 10 points A sigma bond 1. always exists in conjunction with a pi bond. 2. may exist alone or in conjunction with a pi bond. 3. is composed of non-bonding orbitals. 4. stems from sp hybridization of orbitals. 5. is always polar. 004 (part 1 of 1) 10 points In a new compound, it is found that the cen- tral carbon atom is sp 2 hybridized. This implies that 1. carbon is also involved in a pi bond.carbon is also involved in a pi bond....
