Iodination of primary alcohol

WebPrimary alcohols. In a primary (1°) alcohol, the carbon atom that carries the -OH group is only attached to one alkyl group. Some examples of primary alcohols are shown below: Notice that the complexity of the attached alkyl group is irrelevant. In each case there is only one linkage to an alkyl group from the CH 2 group holding the -OH group. http://alevelchem.com/wjec_a_level_chemistry/w11.00.htm
