Question

According to VBT, the formation of a stable bond requires​

Answer 1

Answer:

According to VBT, when two atoms come closer to each other with opposite electron spins, due to mutual rearrangements (or overlapping) of their electron clouds, energy changes are produced. ... Explanation: The direction of the bond formed will be in that direction in which the orbitals are concentrated.

Answer 2

Complete Question:

According to VBT, the formation of a stable bond requires

a) the electrons should have opposite spins.

b) the two atoms should be close to each other.

c) the greater overlapping of the electron clouds

d) all of the mentioned​ above.

Answer:

(d) All of the mentioned above.

Explanation:

According to the valence bond theory, the formation of a stable bond requires the electrons to have opposite spins, Atoms be close to each other and overlapping electron clouds.

The main concept of valence bond theory lies in the covalent bond formation. The stronger the covalent bond, more stable is the bond formed.

• If an electron has same direction spins the chances of them repelling are higher which gives a greater chance for instability.
• For a covalent bond formation, the two atoms share the electrons which can be only possible with them being nearby with lesser distance.
• As they share the electrons there is an automatic possibility of them sharing the electron clouds which gives a strong and stable bond.
