‐ For every halogen substitution you need:‐ Only 1 Hydrocarbon Molecule for all the substitutions as long as it has enough Hydrogens

‐ 1 Halogen Molecule with 2 atoms of the same halogen

HALOGEN SUBSTITUTON REACTION

‐ For every halogen substitution you produce:‐Only 1 Halocarbon Molecule with all the substitutions.‐1 Hydrogen atom less and 1 Halogen atom more

‐ 1 Hydracid Molecule of that Halogen

PERFECT!

‐ An alcohol is an organic compound in which a hydroxyl group replaces a hydrogen atom of a hydrocarbon.

‐ General Formula

R-OH‐ Name it the same as alkanes but

change the ending -e for –ol and add the position of the OH.

‐ If there are more than one OH, don’t eliminate the -e, put their positions, and put a prefix (d,tri,tetra, etc.)

ALCOHOLS

‐ An amine is an organic compoud that contain nitrogen atoms bonded to carbon atoms in rings.

‐ General Formula

R-NH2

‐ Name it the same as alcohols but change the ending -ol for –amine and the hydrocarbon part is named like a branch (except for more than one NH2).

AMINES

‐ An ether is an organic compound containing an oxygen atom bonded to two carbon atoms.

‐ General Formula

R-O-R’‐ Name it by naming both hydrocarbon chains as branches and add the ending ether
