Which Of The Following Is Most Stable Shape?

Chlorine trifluoride has 5 regions of electron density around the central chlorine atom (3 bonds and 2 lone pairs). These are arranged in a trigonal bipyramidal shape with a 175° F(axial)-Cl-F(axial) bond angle.

Is ClF3 stable?

Pure ClF3 is stable to 180 °C in quartz vessels; above this temperature it decomposes by a free radical mechanism to its constituent elements.

What is the geometry of ClF3?

Chlorine Trifluoride (ClF3) represents a Trigonal bipyramidal geometry. If the central atoms contain 5 bond repulsion units and if it doesn’t contain a lone pair on the central atom, the molecule shape is trigonal bipyramidal having a bond angle of 175° F-Cl-F.

What is the shape of xeof4?

Xenon oxyfluoride (XeOF4) is the square pyramidal shape.

Why does ClF3 violate the octet rule?

The ‘octet’ rule is based upon available ns and np orbitals for valence electrons (2 electrons in the s orbitals, and 6 in the p orbitals). Hence, the third period elements occasionally exceed the octet rule by using their empty d orbitals to accommodate additional electrons. …

Is octet rule valid for ClF3?

There are ten electrons three bond pairs and two lone pairs about the central chlorine atom so ClF3 does not obey octet rule.

Does BF3 follow octet rule?

BF3 does not obey octet rule.

Why is SF4 trigonal bipyramidal?

The SF4 Lewis structure is the combination of 34 valence electron and 5 electron pairs around the Sulfur, where there are 4 bonding pairs and 1 lone pair. This electron arrangement is called ‘Trigonal Bipyramidal’. … The reason behind this is that the lone pair prefers one of the equatorial positions.

Is ClF3 a shape?

ClF3 molecules are T-shaped.

Is BF3 planar or nonplanar?

Boron has only 3 valence electrons, so when it bonds with F there will only be 3 electron pairs around the boron atom. Repulsion theory predicts that these three e- pairs should find themselves at the vertices of an equilateral triangle (bond angles of 120 degrees). Thus, BF3 is planar triangular.

What is the weakest geometric shape?

The Triangle is one of the most solid geometrical shapes. But it points out also the weakest areas in hitting, locking, stances, moving and so on.

Which structure of sf4 is more stable?

– So, based on this discussion, we can conclude that structure (ii) will be more stable because there is less repulsion for sulphur lone pair in comparison with structure (i).

What resonance structure is most stable?

Rules for Estimating Stability of Resonance Structures

  • The resonance structures in which all atoms have complete valence shells is more stable. …
  • The structures with the least number of formal charges is more stable. …
  • The structures with a negative charge on the more electronegative atom will be more stable.

What is super octet rule?

A super octet molecule is the one which has more than 8 electrons in an ultimate shell around the central atom.

Is BrF5 a super octet?

Drawing the Lewis Structure for BrF. 5

Note that in the Lewis structure for BrF5, Bromine (B) is in Period Four on the periodic table. This means it can hold more than eight valence electrons. This is called an expanded octet.

Can chlorine have expanded octet?

Sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet.

Why does alcl3 not follow the octet rule?

In some of its compounds, aluminum violates the octet rule by having only six valence electrons. For example, aluminum chloride, AlCl₃, has only six valence electrons around the Al atom. However, AlCl₃ exists only at high temperatures. … In this structure, both Al atoms do satisfy the octet rule.

Does pcl5 follow octet rule?

Phosphorus pentachloride: In the PCl5 molecule, the central phosphorus atom is bonded to five Cl atoms, thus having 10 bonding electrons and violating the octet rule.

Does sicl4 follow octet rule?

It has four Valence electrons and has one too. 345678 exactly eight, exactly eight electrons in total. So it actually obeys the octane. It doesn’t have an incomplete or expanded octave because it has exactly eight electrons.

What is the shape of of4?

Tetrahedral Molecular Geometry. This molecule is made up of 4 equally spaced sp3 hybrid orbitals forming bond angles of 109.5o. The shape of the orbitals is tetrahedral. Since there is an atom at the end of each orbital, the shape of the molecule is also tetrahedral.

What is the hybridisation of XeOF4?

The central atom will use its s-orbital, its p-orbitals and as many of its d-orbitals as needed to mix together to make the hybrid orbitals. So for XeOF4, Xe will need its s orbital and all three its d-orbitals and it’s hybridization state will be sp3d2 or d2sp3.
