given their electronegativity values, which pair of atoms could form a covalent bond?\na. o (3.5) and cl (3.0)\nb. mg (1.2) and o (3.5)\nc. f (4.0) and li (1.0)\nd. al (1.5) and f (4.0)

Answer

Explanation:

Step1: Calculate electronegativity difference for each pair

For pair A: (|3.5 - 3.0|= 0.5) For pair B: (|3.5 - 1.2| = 2.3) For pair C: (|4.0 - 1.0|=3.0) For pair D: (|4.0 - 1.5| = 2.5)

Step2: Determine covalent bond based on electronegativity difference

A covalent bond is formed when the electronegativity difference ((\Delta\chi)) between two atoms is (\Delta\chi<2).

Answer:

A. O (3.5) and Cl (3.0)
