CHEM 219 Module 1 Exam Questions and Answers Graded A+
organic chemistry - Answers the study of all chemicals containing carbon
Catenation - Answers the process or preference of an element to bond with another atom of the same
element
Valence - Answers the number of bonds an atom will form to fill its outermost shell
ionic bond - Answers Formed when one or more electrons are transferred from one atom to another
covalent bond - Answers A chemical bond that involves sharing a pair of electrons between atoms in a
molecule
diatomic elements - Answers molecules composed of only two atoms, of the same elements
polar covalent bond - Answers A covalent bond in which electrons are not shared equally
bond order - Answers the number of bonds between atoms
Unsaturated compound - Answers A compound in which there is at least one double and/or triple bond
between carbon atoms
molecular formula - Answers Conveys the number and type of different atoms present in a compound
structural formula - Answers Conveys the number and type of different atoms present in a compound
and also shows a pattern of connectivity between the atoms in the molecule
isomers - Answers Molecules that have the same number and type of atoms of different arrangements
of the atoms
Constitutional or structural isomer - Answers Compounds with the same molecular formula that have
different connectivity between the atoms in their structural formula
branched chains - Answers Smaller chains of carbon that sprout from the longest chains
rings (cyclic chains) - Answers Ends of a carbon chain connected to each other
heteroatoms - Answers Atoms other than carbon or hydrogen bonded in or to the carbon skeleton at
various positions
functional groups - Answers A specific configuration of atoms commonly attached to the carbon
skeletons of organic molecules and involved in chemical reactions
formal charge - Answers The electrical charge possessed by an atom when bonded in a molecule
resonance structure - Answers Two or more structural formulae of a molecule with identical
arrangements of the atoms but different arrangements of the electrons in each
