The LONG RAW datatype is used for BINARY data while the VARCHAR2 datatype is used for character data. These two are inconsistent with each other. You would want to use the LONG datatype instead.

That being said, it makes much more sense if you are creating the table anew to use the CLOB datatype as the LONG and LONG RAW datatypes may seee their end in the future.
