Passage / Comprehension

Hybridisation theory' used to predict the exact geometry of the molecule after finding the number of bond pairs and lone pair of electrons.

Lone pair electrons in molecule occupy more space as compared to bond pairs of electrons. The geometry of molecule or electrons are in such a way to minimized electronic repulsions.

CORRECT shape and example of the $AB_{n}$ type molecule is ( $A =$ Central atom. $B =$ Surrounding atom)

Options:

Answer:

Solution:

BCl₃ is sp² hybridised with no lone pairs → gives trigonal planar shape (120°)

Other options mismatch: PCl₅ is trigonal bipyramidal, IF₇ is pentagonal bipyramidal, SF₆ is octahedral
