Test: Chemistry Mock Test - 2 - Question 7

BCl3 is a planar molecule because in this molecule boron is

Detailed Solution for Test: Chemistry Mock Test - 2 - Question 7

BCl3 - Boron Trichloride:

BCl3 is electron deficient molecules having six electrons in the valence shell of their respective central atoms
To complete their octets, the central atom in each case can accept a pair of electrons from the chlorine atom of another molecule froming dimeric structures.
However, because of small size of B, it cannot accommodate four big sized Cl atoms around it.
Therefore, BCl3 prefers to exist as monomeric planar molecule in which B atom is sp2 hybridized
