Question

Question 34 of 41 > Consider the compound. What is the IUPAC name for the compound shown? Spelling and IUPAC name:

Answer 1

Lets see step by step for both compounds

First

i) there is no double or triple bond in compound so parent name is alkane

ii) Select longest chain of carbon atoms, in the given structure the longest chain is of 6 carbon atoms so its hexane chain

iii) number the carbon atoms of chain from that end where the substituents are added nearer, here at 2nd position 2 methyl groups are present and at 3rd carbon atom 1 ethyl group is present

iv) name the alkane with its substituent alphabetically

So the Name of compound is

3-Ethyl-2,2-dimethylhexane

Compound 2

i) there is no double or triple bond in compound so parent name is alkane

ii) Select longest chain of carbon atoms, in the given structure the longest chain is of 9 carbon atoms so its nonane chain

iii) number the carbon atoms of chain from that end where the substituents are added nearer, here at 4th position 1 propyl group is present

iv) name the alkane with its substituent alphabetically

So the Name of compound is

4-Propylnonane
