# Which one of the following molecule shows the highest angle

$\begin{array}{1 1}(a)\;H-O-H&(b)\; H-S-H\\(c)\;H-Se-H&(d)\;H-Te-H\end{array}$

Can you answer this question?

$H-O-H > H-S-H > H-Se-H > H-Te-H$
According to VSEPR theory,increases the electronegativity of the central atom ,increases the bond angle.
Hence (a) is the correct answer.
