Question

Given below is the bond angle in various types of hybridisation. Mark the bond angle which is not correctly matched.

• A. ${\text{dsp}}^2-{90}^o$
• B. ${\text{sp}}^3{d}^2-{90}^o$
• C. ${\text{sp}}^{3}d-{90}^o$
• D. ${\text{sp}}^3-{109.5}^o$

Answer 1

The correct option is C ${\text{sp}}^{3}d-{90}^o$

$S{P}^{3}d$ hybridisation means trigonal bipyramidal, $5$ bond pairs and $0$ lone pair.

Trigonal bipyramidal shape has both ${120}^o$ and ${90}^o$ angles.

So the correct option is [C].
