Open in App

Solution

Electrovalent Compounds
Covalent Componds
Constituent particles are ions Mg²⁺ and Cl^-.
Constituent particles are C atom and Cl atom.
In MgCl₂ is formed by transfer of electron from Mg to Cl (ionic bond).
. In CCl₄ is formed by sharing of electrons between C and Cl atom (covalent bond).
MgCl₂ is solid.
CCl₄ is liquid
In MgCl₂ the ions are held by strong electrostatic forces of attraction.
CCl₄ molecules are held together by weak vander waal's forces of attraction.
MgCl₂ is soluble in polar solvents
CCl₄ is soluble in non polar solvent.
MgCl₂ conducts electricity in molten state because in molten state ions are free to move and conduct electric current.
CCl₄ does not conduct electric current.
MgCl₂ undergoes fast ionic reactions, eg.
MgCl₂ + Na₂CO₃ -----> MgCO₃ + 2 NaCl
CCl₄ undergoes slow molecular reactions, eg.
CCl₄ + H₂O -----> COCl₂ + 2 HCl
