Arene Nomenclature - II
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
1-bromo-2-chlorobenzene
The numbering sequence begins with bromine, alphabetically.
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
1-ethyl-2,4-dinitrobenzene
The numbering sequence begins with "ethyl", alphabetically, and proceeds in the direction to give the lowest number sequence at the first point of difference (1,2,4 not 1,4,6).
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
para-chlorotoluene
This is named as a derivative of toluene, making the methyl group carbon #1 by definition.
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
1,3,5-tribromobenzene
The numbering sequence is 1,3,5 regardless of which bromine you begin with!
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
1-bromo-3,5-dimethylbenzene
The numbering sequence begins with "bromine", alphabetically, and proceeds in either direction to give the same number sequence.
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
ortho-bromopropylbenzene
The numbering sequence begins with "bromo", alphabetically, and proceeds in the direction to give the lowest number sequence at the first point of difference (1,2 not 1,6); ortho is an alternative to "1,2".
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
1-fluoro-2,4-dinitrobenzene
The numbering sequence begins with "fluoro", alphabetically, and proceeds in the direction to give the lowest number sequence at the first point of difference (1,2,4 not 1,4,6).
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
2-methyl-6-phenylheptane
The parent chain here is heptane, since it contains more carbons than the ring. The benzene ring is therefore a substituent and is referred to as a "phenyl" group. This molecule could also be named (1,5-dimethylhexyl)benzene.
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below: shown below:
(1-bromoethyl)benzene
The benzene ring is the parent and the 1-bromoethyl group is simply a substituent.
Using the drawing pallet on the right, draw the structure
corresponding to the IUPAC name given below:
para-bromomethyltoluene
Since this is a derivative of toluene, the numbering sequence begins at the methyl group, by default; the bromomethyl group is simply a substituent. Recall that para is an alternative to "1,4".
That is correct!
Sorry, that is not correct. You should modify your
structures and try again.
Note: Nitro groups are shown
using two double-bonded oxygens.
(A pentavalent nitrogen!)
