Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence...

MCAT Organic ChemistryWhat are the four rules for writing resonance structures? - correct answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? - correct answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple b...

Lewis dot structure: steps Correct Answer 1. Find total # of valence electrons for all atoms in molecule 2. Use one pair of electrons to form one bond between each atom 3. Arrange remaining electrons around atoms to satisfy duet for H and octet for other atoms Exceptions to octet rule Correct Answer 1. B, Be: may have less than an octet 2. Atoms with an odd number of electrons 3. Atoms in the 3rd period or greater (with d orbitals available for hybridization) may have greater than an octe...
