Primary alcohols have a hydroxyl on their end, while in secondary alcohols the hydroxyl is somewhere along the carbon chain's length.

Explanation:

Primary alcohols are where the hydroxyl (-OH) group is attached to the first carbon, so includes a -CH_2OH group. The alkyl here is only attached to one other alkyl group, shown below

Secondary alcohols are where the hydroxyl is attached to an alkyl that is attached to more than one other alkyl, so includes the group -CHROH, where R is some other alkyl group. This looks like
