Identify the incorrect statement

AS_2 is paramagnetic like oxygen.BRhombic and monoclinic sulphur have S_8 molecules.CS_8 ring has a crown shape.DThe S-S-S bond angles in the S_8 and S_6 rings are the same.

Show answer and solution▾

The statement "The $v = \frac{\omega}{k}$ bond angle in
the $= \frac{200\pi}{\left( \frac{5\pi}{4} \right)}$ and  = 160 m/s
$\Phi_{1} = \Phi_{2} = \Phi_{3} = \Phi_{4}\$rings are the same." is
incorrect.
Both $C = \frac{\varepsilon_{0}A}{3}$ and
$C = \frac{\left( \frac{k\varepsilon_{0}A}{3} \right)\left( \frac{\varepsilon_{0}A}{2.4} \right)}{\frac{k\varepsilon_{0}A}{3} + \frac{\varepsilon_{0}A}{2.4}}$ molecule
have the same bond length but different bond angles.
The$\frac{\varepsilon_{0}A}{3} = \frac{\left( \frac{k\varepsilon_{0}A}{3} \right)\left( \frac{\varepsilon_{0}A}{2.4} \right)}{\frac{k\varepsilon_{0}A}{3} + \frac{\varepsilon_{0}A}{2.4}}$`<!- ->`3
k=2.4 k+3molecule has a puckered ring with crown conformation,
whereas $\frac{(A - C)}{D}$ molecule has a chair conformation as shown
below.
