If two lone pairs are arranged at 90 o of angle, the repulsions are greater. (b–d) The two lone pairs (red lines) in ClF 3 have several possible arrangements, but the T-shaped molecular structure (b) is the one actually observed, consistent with the larger lone pairs both occupying equatorial positions. Dear student, A total of 9 lone pairs. The steric number of a central atom in a molecule is the number of atoms bonded to that central atom, called its coordination number, plus the number of lone pairs of valence electrons on the central atom. Iodine having valence electrons in the 4th energy level, will also have access to the 4d sublevel, thus allowing for more than 8 electrons. - (UPESEAT), Amity Joint Entrance Examination Only in above arrangement, the two lone pairs are at 180 o of angle to each other to achieve greater minimization of repulsions between them.
