The basic difference between the electron gain enthalpy (Ea) and electronegativity (EN) is -
1. | Ea is the tendency to lose electrons, while EN is the tendency to repel the shared pairs of electrons. |
2. | Ea is the tendency to gain neutrons, while EN is the tendency to attract the shared pairs of electrons. |
3. | Ea is the tendency to donate electrons, while EN is the tendency to attract the shared pairs of molecules. |
4. | Ea is the tendency to gain electrons, while EN is the tendency to attract the shared pairs of electrons. |
Allred Rochow's scale is related to:
1. Electronegativity, radius, and Z*
2. Resonance energy of the molecule, ionisation potential and electron affinity.
3. Bond Polarity, diagonal relationship and periodicity.
4. None of the above.
The statement that "the electronegativity of N on the Pauling scale is 3.0 in all the nitrogen compounds" is incorrect because -
1. Electronegativity of an element is a variable property.
2. Pauling scale is not used to measure electronegativity.
3. The electronegativity of N on the Pauling scale is 12.0
4. None of the above.
