What hybridization is generally utilized by the central atom in a ...
网页2017年10月5日 · Always think about the directionality of each orbital when considering the hybridization. Their directionalities should add up vectorially to give you the appropriate directions and dimensionalities. I got sp^2d, which is also shown below. DETERMINING THE GEOMETRY One thing to be careful about is what the d-electron count is, so that …
Why is PtCl4^2- square planar? - Socratic
网页2015年12月25日 · A good general rule is that if you have either square planar or tetrahedral, a low-spin complex generally forms square planar, and a high-spin complex generally forms tetrahedral. Platinum is not an exception to that statement. To see why, we should consider nickel, which is in the same group, whose complexes are tetrahedral sometimes and …
What is the molecular geometry of BrF4- ? A) square planar B) …
网页2015年4月26日 · A) square planar. The answer is A) square planar. Start from the Lewis structure of the tetrafluoroborate ion, BrF_4^(-). The molecule will have a total of 36 valence electrons - 7 from bromine, 7 from each of the four fluorine atoms, and one extra electron to give the ion the -1 charge. The bromine atom will be bonded to each of the four fluorine …

网页2018年11月30日 · If you think of the structure of the square planar molecule, the lone pairs lie 180 degrees apart at the bottom and top of the structure and the four bonded atoms are in the equatorial plane in the form of a square. Generally a lone pair will distort the angles between the bonded atoms, however because a square planar has two lone pairs on …
Square planar complex vs tetrahedral complex - CHEMISTRY …
网页2020年12月13日 · Re: Square planar complex vs tetrahedral complex. Postby Sunny Wu 3A » Sun Dec 13, 2020 5:32 am. A square planar structure has 2 lone pairs on the central atom (AX4E2) while a tetrahedral structure has no lone pairs on the central atom (AX4). The bond angles of a square planar structure are 90 degrees vs 109.5 degrees for tetrahedral.
Square Planar vs. Tetrahedral - CHEMISTRY COMMUNITY
网页2020年12月9日 · While both tetrahedral and square planar have 4 bonded atoms, square planar also has 2 lone pairs attached to the central atom, this causes the change in shape. A represents the central atom, X represents the bonded atoms, and E represents the lone pairs in the formulas above. The first image is square planar and the second image is …
Why is #"BrF"_4^(-)# square planar, whereas #"BF"_4^(-)# is
网页2016年2月27日 · Hence, square planar, as shown below where green dots came from Br, blue from F, and red is the extra electron providing the overall negative charge. Looking at BF_4 ^-, B only provides 3 valence electrons, so 3 of the F's will bond directly to these, and the fourth F will occupy the open p-orbital of B. Again, an extra electron shown in red ...
Seesaw or Square Planar - CHEMISTRY COMMUNITY
网页2018年11月27日 · Postby taryn_baldus2E » Tue Nov 27, 2018 6:43 pm. Seesaw is when there are 5 regions of electron density with one lone pair whereas square planar has 6 regions of electron density and two lone pairs. It may be easier for you if find the electron region density and then consider where the electrons would exist in order to find the …
tetrahedral vs square planar - CHEMISTRY COMMUNITY
网页2023年11月28日 · Square planar means we have 6 regions of electron density, but only four of which are occupied by an atom, i.e. XeF4. The two other regions are occupied by lone pairs on "opposite ends" of the central atom in order to have the maximum distance from each other due to lone-lone pair repulsion being the greatest.

网页#5#: trigonal bipyramid (a trigonal planar shape with two "spokes") #6# : octahedron (a flat square with two "spokes") Once there are any electron pairs, one spoke of the original shape gets "eaten up": for example, a #AX_4E_2# is an octahedron shape, but the two "spokes" are taken up by electron pairs, so you're left with just the square—a ...
