1st lets place the 5 of them in the given order .

--r BOB l--r PETER l--r OLIVER l--r RAVEN l--r CHELSEY l-- (where the r , l indicates the rights and lefts w.r.t the persons )

Now , take the 2nd condition, i.e; RAVEN sits next to BOB . So shift her there.
--r BOB l--r RAVEN l--r PETER l--r OLIVER l--r CHELSEY l--

Now , the last condition is that no girl sits at the extreme ends or middle.. So we move CHELSEY in place of OLIVER.. (PETER cannot be swapped since he is the middle one.)
So , we get the final arrangement as :
--r BOB l--r RAVEN l--r PETER l--r CHELSEY l--r OLIVER l--

So we now know that its PETER on the right side of CHELSEY.
