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.
2)
Cl2 is covalent as Cl is non metal
KF is ionic because K is metal and F is non metal.
OF2 is covalent as O and F are non metal
HF is covalent as H and F are non metal
H2 is covalent as H is non metal
Answer: B
3)
F2, H2 and N2 are non polar covalent because both the non metals are same.
NaCl is ionic because Na is metal and Cl is non metal.
H2O is polar covalent because both the non metals are different
Answer: A
4)
Cl2 are non polar covalent because both the non metals are same.
Answer: B
