Find attached answer to this question.
Explanation:
a. 4-Isopropyloctane has a chain of eight carbons, with an isopropyl group on the fourth carbon.
5-tert-Butyldecane has a chain of ten carbons, with a tert-butyl group on the fifth.

b. Using this rule, we can construct names for some complicated structures. Let\u2019s fin-
ish naming the heptane on p. 90, shown here in the margin. This compound has an ethyl
group on C3 and three methyl groups on C2, C4, and C5. List the ethyl group alphabeti-
cally before the methyl groups, and give each of the four substituents a location number.
Problem-solving Hint
When substituents are alphabetized,
iso- is used as part of the alkyl group
name, but the hyphenated prefixes
are not. Thus, isobutyl is alphabetized
with i, but n-butyl, tert-butyl, and sec-
butyl are alphabetized with b. The
number prefixes di-, tri-, tetra-, etc.
are ignored in alphabetizing.

Give a systematic (IUPAC) name for the following compound.
SOLUTION
The longest carbon chain contains eight carbon atoms, so this compound is named as an octane.
Numbering from left to right gives the first branch on C2; numbering from right to left gives
the first branch on C3, so we number from left to right.
