For the molecules below, draw all the symmetry elements, and determine the symmetry point group.a) XeF5.b)...
Find and list all symmetry elements present in the molecules
below, and assign a point group to each. Indicate the principal
axis (z axis) on each drawing. Note: Different resonance structures
involving p-bonds do not destroy symmetry elements. You can assume
the highest level of symmetry depicted in the drawings.

Determine the symmetry elements and the Point Group of the following molecules: HCN, SO3, PF5
Assign the point groups of the following molecules (you may have to look up their structures). List all symmetry elements and draw a sketch of each symmetry operation, you may omit repetitive drawings per structure. [10 pts] trans-N2F2 SCIF H30 HCI SOCl2
2. (3 pts) Determine the symmetry elements and assign the point group of: a. trans-1,2-dichloroethylene b. H30+ c. formaldehyde, H2CO
a) Find all the symmetry elements of 1,1-dichloroallene and 1,3-dichloroallene. Please draw the structures of the molecules and show the location and nature of the symmetry elements Find the point group of both molecules. Are any of the two isomers chiral? If so, which? Depict the stereoisomers if you find chirality
2.) Give the point group assignment of the following transition metal compounds: a.) trans- [PtCl2Br2]the ion has a square planar shape with Pt as the central atom b.) [CO(NH3)sBr]? the ion has an octahedral shape with Co as the central atom. Treat the NH3 groups as a large, spherical atom attached to the Co. c.) [Fe(CO)s) the compound is a square pyramidal shape, with Fe as the central atom. Assume that the Fe-C-O bond angle for each attached CO is...
1. (a) Different conformations are found in pentane. (i) Using Newman Projection, draw all the possible staggered and eclipsed conformations of pentane by referring to the bond rotation at C2-C3. (ii) Compare their stability and explain your answer. (b) Draw the most stable form of the chair conformers for trans- and cis-1,4-dimethyl cyclohexane. Comment on their stability. thanks
For the following molecules, determine geometries, symmetry elements, the formal charge of central element and symetry point group : HOCl, PCl3, SF4, HBrO
All parts please!!
1. Determine the point group for each of the following molecules. If the molecule has a C,axis, draw and label the axis on the molecular structure. Similarly, draw all mirror planes that are present in the molecule. Feel free to draw multiple copies of a molecule to show the symmetry elements more clearly. NH3 b) Br NH / 111111 -Cr F- Cr. OH OH2 ço e) Çih f) CO IZ ОН CO g) F.
1)Sketch symmetry elements that

group?
2)For the following molecules,
determine the number of IR active C-O stretching vibrations. Which
point group is each molecule?
