Question

Which of the following characters do not support the formation of a covalent bond between two atoms:

• A. The electronegativities of both then atoms should be high.
• B. The difference of electronegativities between the two atoms should be minimum.
• C. Less atomic size to the both atoms
• D. The difference of electronegativities between the two atoms should be maximum

Answer 1

The correct option is D The difference of electronegativities between the two atoms should be maximum

Option D is correct because it does not support the formation of a covalent bond between two atoms,because if the difference of electronegativities between the two atoms should be maximum there will be transfer of electrons take place as one atom has less size and it attracts the electrons of other atom which leads to the gain of electrons and proceeds to form ionic bond
Hence option D is correct.
