- 1AlcoholsAlcohols are hydroxyl derivatives of hydrocarbons in which one or more hydrogen atom are replaced by OH group
- 2Glycols2 OH groips are attatched tovdifferent carbon atom
- 3Glycerols3 OH groups are attached
- 4sorbitol
- 5Allylic alcoholNext to next double bond
- 6Vinylic alcoholNext to double bond
- 7Benzylic alcohols
- 8girgnards wantsactive hydrogen
- 9p , s= t=- aldehyde/ketone
-alkene - 10AS ALKYL GROUP INCREASE ACIDIC NATURE OF OH BONDDECREASES DUE TO INCRE IN ELECRTRON DENSITY ON OXYGEN AND DECREASE IN POLARITY
- 11boiling point-increases with increase in the number ofc atomes due to increase in the van der waal forces
-high bp due to hydrogen bonding
- increases with molecular mass
- decreases with branching - 12solubilitydecrease with increase in size
- 13alcohol structure points--->similar to the structure of water and o
---->o is sp3 hyb
----->C is sp3 hyb
----->c-o are bonded by sigma bonds
----> sp3 of c and sp3 of o overlap
----->o has 2 lone pairs so due to replusion d bondangle of c-o is less than the tetrahedral - 14physical propertiesLOWER MEMBERS- colorless liq.
higher members -solids and colorless
ALCOHOLS have higher bp than many other corresponding groups
