Explain Valence Bond Theory. |
|
Answer» SOLUTION :The covalent bond is formedby overlapping of those orbital which contains unpaired electrons. When the overlapping is ALONG axis, the overlapping becomes maximum and strong, called as a SIGMA bond. During overlapping the electrons present in the valence orbit must have opposite SPIN. Covalent molecule have lower energy than COMBINING atoms. Therefore resulting molecule are always stable. |
