HELP!! Due tomorrow!! Bond Angles of molecular structures?

Question

Predict the bond angle for each molecule of ion in part a, b, c. ^ means exponent. Numbers after letters is subscript.a) POCl3, SO4^2-, XeO4, PO4^3-, ClO4^- (tetrahedrals)b) NF3, SO3^2-, PO3^3-, CLO3^- (trigonal pyramidal) c) ClO2^-, SCl2, PCl2^- (bent or angular)I think each one of them SHOULD have a different bond angle.. but then i’m thinking maybe they all share the same bond angle since they are in the same group…. I don’t know…Please help me!! I’m so lost and I need to get this done by midnight tonight. Any help would be appreciated THANK YOU VERY MUCH!!!

For (a), the angles will all be 109.47 degrees (tetrahedral angle), except for POCl3. In that case, the P-O bond acts as if it needs more space, so it pushes the P-Cl bonds closer to one another. The Cl-P-Cl angles will be less than 109.47, while the O-P-Cl angles will be a little larger. (b) Similar: the molecules/ions will all have bond angles slightly less than 109.47 degrees, since the non-bonding pair of electrons pushes the bonds away. (c) Now you have two nb pairs pushing on the bond pairs, so the angles will again be smaller than 109.47… because of the two nb pairs, they will actually be smaller than the angles in the molecules/ions in (b).

For the best answers, search on this site shorturl.im/GlqeHA) Tetrahedral B) Trigonal Planar 109.5 C) Trigonal Pyramidal

Dr. Reggie Bosco DVM · Answer

a) Tetrahedral… I believe the angle is 109.5.b.) Trigonal Pyramidal… I believe it is 107c.) Bent or angular… I believe it is 105.Taken from meh chem book.
