Question

SnCL2 is solid while SnCl4 is liquid ...?

Answer 1

As the oxidation state of a metal increases, its electronegativity increases and the bonds become increasingly covalent. SnCl2 forms a network solid where the atoms are bonded to one another throughout a network of polar covalent bonds. SnCl4 is molecular, and held together by weaker intermolecular forces called London dispersion forces.
