Drylab 3 free essay sample

BrF3 has trigonal bipyramid electron group arrangement (3 bonds+2 lone pairs) but not corners are occupied by identical atoms (2 have lone pairs of Br) so the dipole moments do not cancel out and the molecule has a net dipole moment SF4 has again trigonal bipyramid electron group arrangement (4 bonds + 1 lone pair) with one lone pair at one of the corners so, it has a net dipole moment SF6 has octahedral electron group arrangement (6 single bonds) and since all corners have F atoms the dipole moments of the bonds cancel each other and the molecule has no net dipole moment. 1. 2 What is the orbital hybridization of a central atom that has one lone pair and bonds to: (a) two other atoms ;(b) three other atoms ;(c) four other atoms; (d) five other atoms? Answer: If the central atom has one lone pair and 1Â  other atom: sp hybrid 2 other atoms: sp2 hybrid 3 other atoms: sp3 hybrid 4 other atoms: sp3d hybrid 5 other atoms:sp3d2 hybrid a.

The Lewis structure of BrF3 has 5 electron pairs 3 bonding and 2 nonbonding ,therefore it follows sp3d hybrid (b). similarly, BrO- sp3 hybrid and (c)BrF5 sp3d2
