Q. In which of the following molecules are all the bonds not equal?
Rajasthan PETRajasthan PET 2012
Solution:
In $ Cl{{F}_{3}} $ all bonds are not equal due to trigonal bypyramidal ( $ s{{p}^{3}}d- $ hybridisation) geometry of $ Cl{{F}_{3}} $ molecule.
$ B{{F}_{3}} $ and $ Al{{F}_{3}} $ show trigonal symmetric structure due to $ s{{p}^{2}}- $ hybridisation.
$ N{{F}_{3}} $ shows pyramidal geometry due to $ s{{p}^{3}} $ hybridisation
