Chem 219 Module 2 with correct
questions and answers
, list prefixes for first 10 carbons in order - correct ans:meth, eth, prop, but,
pent, hex, hept, oct, non, dec
hydrocarbon - correct ans:compounds composed of only carbon and
hydrogen
parent chain - correct ans:longest continuous chain of carbon atoms
substituent - correct ans:heteroatom or group of atoms that are attached to
the parent chain
numerical prefixes for # of identical substituent groups (2-10 in order) -
correct ans:di, tri, tetra, penta, hexa, hepta, octa, nona, deca
alkane (with formula) - correct ans:hydrocarbon containing only single bonds
between carbons, CnH2n+2
rules for naming alkanes - correct ans:1. longest continues chain is parent
chain
2. number parent chain starting with the end closest to the first branch
3. name using IUPAC rules for substituents
IUPAC systematic name order for alkanes - correct ans:locant-
(prefix)SubstituentParent
in numbering parent chains, if there are two equally long chains... - correct
ans:select the chain with the most branches coming off
in numbering parent chains, if the first branch point if the same distance
from either end of the parent chain... - correct ans:choose the numbering
that gives the lower numbers to the most substituents
