CO₂

b.

d.

KCl

e.

CaCl₂

Answer 1

atoms has than tot have Molecules in which two bonded electronegativity difference less only covalent bond. and b contains one So, or have compound a more covalent bonds. G D Electronegativity = 0089 la) O=C =0 so, more than teu ono covalent 7 T 2.55 3.44 bond Cars 2.58 D Electronegativity = 1058 so, one covalent bond so, option to and b will be correct.
