Question

The M.P of snCl4

is less than that of snCl2

. The suitable reason for the observed fact is[ ]

a) there is more charge on sn+4 b) the size of sn+4 is small

c) sn+4 has high polarising power d) the shape of sncl4 tetra hydral​

Answer 1

The M.P. of SnCl₄  is less than that of SnCl₂.  The suitable reason for the observed fact is ( c) Sn⁴⁺ has high polarising power

- As the oxidation state of a metal increases, its electronegativity increases and it polarises the atoms more effectively.

- Due to the high polarising power, the bonds become increasingly covalent.

- Thus, SnCl₄ is covalent in nature and SnCl₂ is ionic.

- As the melting point of covalent compounds is less than that of the ionic compounds, so the M.P. of SnCl₄  is less than that of SnCl₂.
