Answer 1

10)

ionic bond is formed between a metal and a non metal

covalent bond is formed between 2 non metals.

In covalent bond:

If both non metals are same, the bond is non polar covalent or pure covalent.

If both non metals are different, the bond is polar covalent.

In HF, there is electronegativity difference between 2 non metals. SO, this is polar covalent
