The pentahalides are more covalent then trihalides because higher the number of shared electron more will be covalancy so pentahalides are shared between five chlorin atoms these are genrally formed by the group 14 elements

Hey !!
Higher the positive oxidation state of central atom, more will be its polarising power which, in turn increases the covalent charater of bond formed between the central atom and the other atom.
As, in pentahalides, the central atom is in +5 oxidation state while in trihalides it is in +3 oxidation state. Therefore, pentahalides are more covalent then trihalides.
Hope it helps you !!
