Answer:
a) pentane
b) 1,3-dimethyl butane
c) 3,4-diethyl-5-methlyl heptane
d) 1,3,5-triethyl-2,4,6-trimethyl cyclohexane
Step-by-step explanation:
The essence of IUPAC nomenclature is to provide a generally accepted nomenclature for chemical compounds which enables the structure of a compound to be drawn from its name without ambiguity.
In order to name straight chain organic compounds, we have to identify the parent chain and then give numbers to the substituents or locants such that they have the lowest possible numbers in alphabetical order.
The correct names of the organic compounds in the question are;
a) pentane
b) 1,3-dimethyl butane
c) 3,4-diethyl-5-methlyl heptane
d) 1,3,5-triethyl-2,4,6-trimethyl cyclohexane
