What is the total number of π electrons?
What is the number of delocalized π ring electrons?
There are several aromatic compounds with the formula C3H3CI. Name those that have a trisubstituted ring where the methyl groups are
oriented meta.
If you choose to use ortho, meta, or para in your name, abbreviate these prefixes with o, m, or p.
If there are not 3 isomers that fit the description, leave the appropriate number of spaces blank.
Isomer #1:
Isomer #2:
Isomer #3:
DETERMINE EACH ITEM IF TRUE OR FALSE
1. The circle in a benzene ring represents the electrons that are moving in the entire molecule
2. A Carbon-Halogen bond is stronger as you go up the periodic table
3. C10H18 is gaseous in nature
4. Ethers can be explosive when oxygenated
5. In order for a compound to be categorized as aromatic, it must have a p orbital on every atom.
