Hint: We know that Mulliken scale is used for finding electronegativity. It measures the tendency of an atom to attract electrons.
Step by step solution:
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The attraction that a bonding pair of electrons feels for a particular nucleus depends on:
* the number of protons in the nucleus;
* the distance from the nucleus;
* the amount of screening by inner electrons.
The Mulliken scale simply considers the electronegativity of an element as the average of the ionization potential and the electron affinity of that element. The EA and IE refer to the valence state of the element in a compound.
\[{{X}_{M}}=\dfrac{IE+EA}{2}\]
And here,
\[{{X}_{M}}\]= electronegativity of an element,
IE = ionization energy,
EA = electron affinity.
The Pauling scale is the most commonly used. So, Pauling scale electronegativity = (Mulliken scale electronegativity) / 2.8.
So, from the above explanation we can say that the correct answer is “C”.
Note: If there is no electronegativity difference between two atoms, it leads to a pure nonpolar covalent bond. And there is a very small electronegativity difference in polar covalent bond and large difference lead to ionic bond.
