Answers
When ever a bond is formed, it has a bond length to it. The smaller the bond length the stronger is the bond, the longer the bond length the weakest is the bond.
Now, in this case, even though the molecular mass is slightly similar the bond lengths are not. The Br-Br bond contains a longer bond length than a I-Cl bond length. Hence the Br-Br bond is weaker and easier to break.
Answer:
The correct answer to this question is because the intermolecular interactions are greater in high polarity compounds, they often have higher boiling points than low polarity ones.
Explanation:
Given - The boiling point of ICI is nearly 40 degrees c greater than that of Br2.
To Find - Both these substances have nearly the same molecular mass. this is because.
Because the intermolecular interactions are greater in high polarity compounds, they often have higher boiling points than low polarity ones.
Because of these intermolecular tensions, it requires more energy for the molecules to separate. Since I and Cl have distinct electronegativities in this situation, chlorine is polar while bromine is non-polar.
Every bond that is created has a bond length associated with it. The strength of a bond increases with bond length; the weakest bonds have the longest bond lengths. Despite the relatively comparable molecular masses, the bond lengths do not match. Compared to an I-Cl bond, the Br-Br bond has a larger bond length. As a result, the Br-Br bond is weaker and more easily broken.
