6! ways
suppose we have 6 chairs A,B,c,D,R,F. 1st child sits on chair A. Fix 1st child on A. Now , 2nd, 3rd, 4th, 5th and 6th child can sit on chairs B,C,D,E,F.
Again fix 1st chiled on A and keep changing the chairs of remaining children. This will result in 5! ways.

so the arrangements can be done as
6*5*4*3*2*1= 6!
720 ways
