Question

1) To form ionic bond the electronegativity difference between two atoms must be greater than a) 0.9 b) 2.1 c) 1.7 d) 3.0 ​

Answer 1

Answer:

1.7 is for ionic bond

0.4 to 1.7 polar covalent bond

Answer 2

Answer:

well the in general the electronegativity difference for an ionic compound should be greater than 2 you and the electronegativity difference for a polar covalent compound should be in between point 5 to 1.6 and for non polar covalent compounds the electronegativity difference should be less then 0.5
