Faculty of Allied Medical Sciences Organic chemistry (MGOC-101)
Supervision: Prof.Dr.Shehata El-Sewedy Dr. Fatma Ahmed Alcohol, phenols and ether
Outcomes By the end of this lecture, the students will be able to 1-Recognize physical properties for alcohol 2-Known nomenclature of aliphatic and aromatic alcohol 3- learn preparation of aliphatic and aromatic alcohol 4- known reaction of aliphatic and aromatic alcohol 5-Differentiate between aliphatic and aromatic alcohol 6- Understand the order of acidity
Alcohol ROH as function group of alcohol AromaticAlcohols (Phenols)
Physical properties Alcohol soluble in polar solvent (H2O) Alcohol have high boiling point due to have intermolecular hydrogen bond So alcohol its boiling point higher than corresponding alkane, ether which have the same number of carbon ROH> R-H> R-O-R Alcohol Alkane ether
As number of OH group increase hydrogen bond increase, boiling point increase & viscosity increase.
Nomenclature 1-Common name Alkyl name+alcohol 2-IUPAC 1-Select the long continuous chain have OH as parent name (alkane alkanol) 2-Number from side near to OH group to give lowest number (position+alkanol) 3-Substitution its position& name write 4-Priority in numbering of groups -COOH>-CHO>-CO->-OH>alkene>alkyne>R
Preparation of alcohol 1-Reduction of carbonyl group
Reaction of alcohol 1-Oxidation of alcohol
2-Esterification EX:
AromaticAlcohols (Phenols) Nomenclature
Preparation of phenols From halobenzene
Reactions of phenols Ether formation Ex.
The order of acidity RCOOH ˃ Ar-OH ˃ HOH ˃ R-OH Phenol is more acidic than alcohols because:-
Arrange for the order of acidity: R-OH - RCOOH - HOH - Ar-OH Convert: Chlorobenzene
Write the nomenclature for the following compounds Write the chemical formula for the following compounds?
