Question

1. What happens to the bond length when
unsaturation increases?
​

Answer 1

Answer:

As a general trend, bond length decreases across a row in the periodic table and increases down a group. Atoms with multiple bonds between them have shorter bond lengths than singly bonded ones.

Answer 2

When  unsaturation increases then bond length will decrease.

Explanation:

• Unsaturation means when a compound or substance contains a double or triple bond. More is the amount of unsatuartion present in a compound more will be the overlapping present over there.

• Also, it is known that more is the overlapping present more will be the bond strength. And, bond strength is inversely proportional to bond length. This means that more is the bond strength lesser will be the bond length.

• Hence, it shows that when there will be increase in unsaturation then there will occur a decrease in bond length of the compound. Similarly, lesser is the unsaturation present more will be the bond length.
