Question 4 of 25aFor a bond to be covalent, the electronegativity difference between the atomsmust be:OA. zero.B. less than 1.7.OC. less than 0.5.D. over 2.
A covalent bond can be polar o non polar, but if the electronegativity difference between the atoms is less than 1.7 will be covalent polar and it will be covalent nonpolar if it is less that 0.5.
