1. nomenclature challenge: name the following lewis, condensed and line - angle structures using iupac rules: a. b. c. d. (ch3)2chch2ch2c(ch3)3 e.
Answer
Explanation:
Step1: Identify parent - chain for a
The parent - chain is an octane ring. There are two substituents: a methyl group and an isopropyl group. Number the ring to give the lowest sum of locants. 1 - isopropyl - 4 - methylcyclooctane
Step2: Identify parent - chain for b
The longest continuous carbon - chain has 12 carbon atoms. There are methyl substituents at positions 4, 5, 7. 4,5,7 - trimethyldodecane
Step3: Identify parent - chain for c
The longest continuous carbon - chain has 8 carbon atoms. There are methyl, ethyl and propyl substituents. Number the chain to give the lowest sum of locants. 3 - ethyl - 4 - methyl - 5 - propyloctane
Step4: Identify parent - chain for d
The longest continuous carbon - chain has 7 carbon atoms. There are methyl substituents. 2,2,6 - trimethylheptane
Step5: Identify parent - chain for e
The longest continuous carbon - chain has 10 carbon atoms. There is a methyl substituent at the 4 - position. 4 - methyldecane
Answer:
a. 1 - isopropyl - 4 - methylcyclooctane b. 4,5,7 - trimethyldodecane c. 3 - ethyl - 4 - methyl - 5 - propyloctane d. 2,2,6 - trimethylheptane e. 4 - methyldecane
