Question

| https://digital. 16245 Docs w 454 05 Question 1 point) The type and magnitude of intermolecular forces present in a sample of a pure substance depend largely on whether the molecules are polar or nonpolar. Being able to quickly Identify molecular geometries that are likely to be polar Is a helpful ski" for chemists. An of the ball-and-stick representations shown here are molecular geometries (not electron pair geometries). 1st attempt Part 1 (0.2 point) Feedback see Periodic Table See Hint Assuming that the electron-pair geometry of the two ball-and-stick representations is identical, what is the hybridization on the central atom?

Explanation / Answer

part 1)

As the electron pair geometry is same, one of them is trigonal planar and the other is anglular.

Thus the hybridization should be sp2.[ with a lone pair the structure can't be planar trigonal]

OPTION B

part 4 )

OPTIONS B and C

All have same electron geometry, but a is symmetric structure. B and C are not, thus they have lonepairs and unsymmetric structure thus they are polar

part 5)

All have same number of electron pairs that is 5 and the structure has trigonalbipyramidal geometry. Thus it has no lone pair and the hybridization is sp3d.

OPTION D

part 6)

All structures B, C and D are polar as they are NOT symmetric structures.

options B,C,D
