Question

Compare bond lengths for the following molecules.

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

Answer 1

The correct option is A $x>y$

The atomic size of $Se$ is higher than the atomic size of $S$.Hence, with increases in the atomic size, the bond length also increases.Hence, the bond length $x$ is greater than the bond length $y$.
$x=168$ pm; $y=153.9$ pm
