Chemical Bonding And Molecular Structure Ques 92
92. In a regular octahedral molecule, $M X_6$ the number of $X$ - $M$ - $X$ bonds at $180^{\circ}$ is
[2004]
(a) three
(b) two
(c) six
(d) four
Show Answer
Answer:
Correct Answer: 92.(a)
Solution:
(a)

Thus here bond angles between
$ \begin{aligned} & X_4-M-X_2=180^{\circ} \\ & X_1-M-X_3=180^{\circ} \\ & X_5-M-X_6=180^{\circ} \end{aligned} $
