Dear Mahendra B Thapa,
displaying bonds between atoms depends on the file format used, and on
the distances between the atoms involved in the bonds.
when using the pdb file format in LEaP this depends on the presence of
atomic connectivities with the Cartesian coordinates in the file.
when using LEaP - if the atomic connectivities are absent you need to
use the 'bondbydistance' command to create the bonds (based on the
atomic distances; i.e. if below an internally defined threshold a bond
between two atoms is created)
when using the mol2/mol3 file format (or off file format) the bonds
reported in the file are displayed (even if above the threshold).
