and boiling point while covalent compounds have
low melting and boiling points.
(c) Electrovalent compounds dissolve in water whereas
covalent compounds do not.
(d) Electrovalent compounds are usually hard crystals.
(e) Polar covalent compounds conduct electricity.
(f) Water is a polar covalent molecule ?​

Answer 1

Answer:

Electrovalent compounds conduct electricity

• Electrovalent compounds have a high melting points
• Explanation:
• because they have free ions that can move
• electrovalent bonds are strong bonds and it is in a chain form so it is hard to break all the chains so it is so strong
