Question

Compare bond length from the following molecules.

• A. $x>y$
• B. $y>x$
• C. $x=y$
• D. None of these

Answer 1

The correct option is B $y>x$

The bond length $y$ is greater than the bond length $x$. The molecular geometry of both the molecules is same. In the first molecule, $Cl$ is used which has a shorter bond length than $Br$ used in the second molecule. Hence,$y>x$.
