Dear Dr. Justin,

Thanks for the explanation. Now i got the point you mentioned here. Then i
checked the bonds i have mentioned in .rtp file and then i found the
relevant bonded type. then i checked the ffbonded.itp file and i found that
bond type is already in there.
As an example,

CAY  HA1 ; this is one of bond i have in .rtp file. and for that bond,
relevant bond type (mentioned as below) was already in ffbonded.itp file
CT    HC      1    0.10900   284512.0

But still following error is occurring while running grompp.

1) ERROR 1 [file topol.top, line 108]:
  No default Bond types

2) ERROR 2 [file topol.top, line 168]:
  No default Angle types

3) ERROR 3 [file topol.top, line 426]:
  No default Ryckaert-Bell. types

How do i refer particular bond types in ffbonded.itp file to my current
.gro file or any other relevant file ?

grompp won't complain about parameters being missing if they're actually there. You're probably looking at the wrong line.
