Question

Hybridisation is a theoretical concept, as state of hybridisation can not be detected ever the spectroscopically: unlike intermediates or transition state in various reactions but it corrects the predictions which are based on overlapping of pure atomic orbitals. VSEPR theory predicts precisely shape and bond angle in a given molecule.
Which of the following molecule /ions which are not planr?
A. `[IF_(4)]^(-)`
B. `[IF_(4)]^(+)`
C. `[NH+(2)]^(-)`
D. All of the above are planar

Answer 1

(A) `[IF_(4)]^(-)rarr` Square3 planar
(B) `[IF_(4)]^(+)rarr` See saw
(C ) `[NH_(2)]^(-)rarrV//` Bent planar
