Answer 2

Br2 has the longest bond length. (229 pm)

• The bond length is one of the most important chemical characteristics of any chemical molecule.
• If we observe the periodic table, there is a trend that the bond lengths increases as we move down through a group of the periodic table.
• And, among the given molecules, the Br is situated in the most below position in the periodic table.
• So, the largest bond length will be obtained by the Br2 itself which is around 229 pm.
