ANSWER:
Solution 82P :
Step 1:
Here, Referring to given Figure 10.2 we need to find the electronegativity difference between each pair of elements and then refer to Table 10.2 classify the bonds that occur between them as pure covalent, polar covalent, or ionic.
Table 10.2 The Effect of Electronegativity Difference on Bond Type
Electronegativity Difference (ΔEN) |
Bond Type |
Example |
zero (0–0.4) |
pure covalent |
Cl2 |
intermediate (0.4–2.0) |
polar covalent |
HF |
large (2.0+) |
ionic |
NaCl |
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons, towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.
