Phenols
-OH group attached to a benzen ring = phenols
What organic compounds have boilingpoint similar to that of alkanes?
Ethers
Ethers solubility:
They are slightly soluble in water , but they mix well with other non-polar molecules such as alkanes
Thiol
• Functional group: SH (thiol group or sulfhydryl group) • the bond between S and H is called is called sulfur-hydrogen bond • they have similar molecular structures as those of alcohol
Thiols = ?
Mercaptans
What organic compounds smells like garlic?
Thiol
What is the main odour constituent?
T-butyl mercaptan
Poisoning of thiols?
Precipitation of these enzymes or protiens containing -SH groups by heavy metal ions such as hg+ causes these compounds to be poisonous
Methyl phenols = ?
Cresols
How are phenols converted to ethers?
Williamsons synthesis
Polyhydric alcohols
Contain more than one -OH group in the molecule. • e.g saccharides • e.g ethane-1,2-diol
Give examples of two alcohol isomers:
Propan-1-ol and propane-2-ol are isomers
