| Allylic alcohol | Next to next double bond |
| Vinylic alcohol | Next to double bond |
| Benzylic alcohols | |
| girgnards wants | active hydrogen |
| p , s= t= | - aldehyde/ketone -alkene |
| AS ALKYL GROUP INCREASE ACIDIC NATURE OF OH BOND | DECREASES DUE TO INCRE IN ELECRTRON DENSITY ON OXYGEN AND DECREASE IN POLARITY |
| boiling 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 |
| solubility | decrease with increase in size |
| alcohol 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 |
| physical properties | LOWER MEMBERS- colorless liq. higher members -solids and colorless ALCOHOLS have higher bp than many other corresponding groups |
