Electronegativity values for elements are useful in predicting
Electronegativity values for elements are useful in predicting
The correct option is D All
For determining bond energy, lets take a look at the bond strength first.
Bond strength: If the electronegativity difference of 2 covalently bonded atoms (Δx) increases, the bond energy of the covalent bond also increases. For example - the order of the H - X bond strength is H - F > H - Cl > H - Br > H - I
So, we can say that electronegativity values are useful for predicting bond energy of a molecule compound.
Now, partial ionic character in covalent Bond: The ionic character of a covalent bond increases as the electronegativity difference of bonded atoms increases.
Therefore, it can be used to predict the polarity of a molecule because there will be a partical negative charge on the atom which is more electronegative.
Now, about the nature of oxide.
In general, the electropositive / electronegative character of the oxide's central atom determines whether the oxide will be acidic or basix. The less electronegative/more electropositive the central atom, the more basic the oxide. The more electronegative the central atom, the more acidic is the oxide.
Therefore, electronegativity values for elements are useful for predicting all these characteristics.
