Co-ordinate Bonds - Chemical Bonding and Molecular Structure
|
Co-ordinate Bond:
(a) Favourable conditions to form Metallic Bond:
· One of the group or or atom must have a lone pair of electrons whereas the other must have the incomplete octet or duplet.
· Also known as dative bond
(b) Properties:
· Intermediate between ionic and covalent compounds
· Sparingly soluble in water, not forming ions, largely soluble in non-polar solvents
· Melting and boiling points are higher than purely covalent compounds but less than purely ionic compounds
· Stable as covalent compounds, addition compounds are very stable
· Non conductor
· Bond is rigid and directional
· High value of dielectric constant
