the to identical rows

We Normally provide PRIMARY KEY in every Table.
But Sometimes we forget or for some reason we do not provide primary
key in table.
In that case it is very difficult to delete one of the two duplicate
records

Just an Example:
======================================
DEPT_ID DEPT_NAME
10 CHEMICAL
10 CHEMICAL
10 CHEMICAL
======================================

Here I Entered Three duplicate records my mistake and I want to keep
only One Unique Record, So if would have been Any Feature to Uniquely
Identify the Row I would be able to Delete that row using that UNIQUE
ID as Oracle Supports.
