Why pcl5 is more covalent than pcl3?

Posted by Dheerendra Kumar 8 years, 2 months ago

CBSE > Class 12 > Chemistry

1 answers

Nitya Chugh 8 years, 2 months ago

The oxidation state of +5 in pentahalides is more as compared to +3 oxidation state in trihalides. Due to the higher positive oxidation state of central atom in pentahalide state, these atoms will have larger polarizing power than the halogen atom attached to them. Therefore pentahalides are more covalent.
