Question

Give three differences in the properties of NaCl a typical electrovalent compound and CCl4
a typical covalent compound

Answer 1

Difference between Electrovalent Nacl and covalent Ccl₄ .

Nacl :

• this is a electrovalent bond.
• these bonds are formed by transfer of electrons from one atom to the other.
• electrovalent bonds can be observed in metals and non- metals.
• Boiling point of Nacl is high than Ccl₄ .
• Difference in electroneagitivy of both atoms is higher than Ccl₄
• solubility in water is more compared to Ccl₄
• electrical conductivity of Nacl is more than Ccl₄

Ccl₄ :

• This is a covalent bond.
• These bonds are formed by sharing of electrons between atoms.
• These bonds are observed mostly in non - metals.
• Boiling point of Ccl₄ is less than Nacl.
• Difference in electroneagitivity is less compared to Nacl.

• solubility in water is less compared to Nacl .
• electrical conductivity of Ccl₄ is less than Nacl.
