The general formula of alcohol |
CnH2n+1-OH |
|
|
Explain the physical properties of alcohol and what are they influenced by? |
They are influenced by their ability to form hydrogen bonds (intermolecular force). Hydrogen bonds form between the OH groups of neighbouring alcohol. These intermolecular forces occur between electron deficient H + one one alcohol and the lone pair of electron on an O- on another alcohol molecule. |
|
|
Draw a hydrogen bond between two molecules. |

|
Why do alcohol dissolve in water? |
Because hydrogen bonds form between the polar O-H functional group and the polar water molecule. |
|
|
Explain the classification of alcohol. |
A primary alcohol has 1 alkyl group, secondary 2 alkyl group and tertiary has 3 alkyl group attached to the alpha carbon. |
|
|
Alcohols are oxidised by using ... |
Acidified dichromate solution. Heat is required. |
|
|
During oxidation of alcohol what colour observation would you see on acidified dichromate solution. |
