The axial bond is 158 pm and the equatorial is 152 pm.
One explanation is that the hybridisation of the equatorial bonds is sp2 and the hybridisation of the equatorial is pd, the greater s character of the equatorial making the bond shorter. (taken from text book Inorganic chemistry by House)
I know of no theretical study that backs this up.
Most text books duck this ,e.g Greenwood and Wiberg.

What is the structure of PCl3F2?
It's a Trigonal-Bipyrimidal So, P is the central atom, while the Cl and F atoms surround it :)
How do double bonds affect the molecular geometry of a compound?
Double bonds in a compound can affect the molecular geometry by restricting the rotation around the bond, leading to a planar or linear shape. This can influence the overall shape and properties of the molecule.
How many pi bonds in BCl3?
BCl3 has no pi bonds. It consists of three sigma bonds formed between boron and each chlorine atom, resulting in a trigonal planar molecular geometry.
Why is the bond lengths in PCl5 unequal?
The structures for the phosphorus chlorides are invariably consistent with VESPER theory. The structure of PCl5 depends on its environment. Gaseous and molten PCl5 is a neutral molecule with trigonal bipyramidal . The hypeRVALENT nature of this species can be explained with three-center four-electron bonding model. This trigonal bipyramidal structure persists in non-polar solvents, such as CS2 and CCl4.In the solid state PCl5 is ionic, formulated PCl4+ PCl6−.
What molecular geometry exists when a central carbon atom bonds to four other atoms?
The molecular geometry is tetrahedral when a central carbon atom bonds to four other atoms. This means the four atoms bonded to the central carbon atom are arranged in a way that resembles a pyramid with a triangular base.
Why axial bonds are larger than equatorial bonds?
axial bonds are longer than equatorial bonds becz axial bond contain very less "s" character as compare to equatorial bond, hence probability of finding it near nucleus is less hence force of attraction by nucleus is less as compare to to equatorial bonds
What is the geometry the compound for dsp3 hybridization?
The geometry for a compound with dsp3 hybridization is called trigonal bipyramidal. It consists of five electron pairs arranged in a trigonal bipyramidal shape, with three equatorial bonds and two axial bonds.

What is the electronic geometry of methane?
All of the hydrogens on methane are evenly spaced apart at 109.5 degree bonds. This makes the geometry tetrahedral.
Why all the 5bonds in pcl5 are not equivalent Explain?
In phosphorus pentachloride (PCl₅), the five P–Cl bonds are not equivalent due to the molecule's trigonal bipyramidal geometry. The three equatorial bonds are arranged in a plane at 120-degree angles to each other, while the two axial bonds are oriented perpendicular to this plane at 180 degrees. This difference in spatial arrangement leads to variations in bond lengths and angles, resulting in the bonds having slightly different characteristics. Consequently, the five P–Cl bonds exhibit different environments, making them non-equivalent.
The electron geometry of the bonds and lone pairs around the oxygen is water is?
tetrahederal.
How do double bonds affect the molecular geometry of a compound?
Double bonds in a compound can affect the molecular geometry by restricting the rotation around the bond, leading to a planar or linear shape. This can influence the overall shape and properties of the molecule.
What is the molecular geometry for CH3I?
Since there is 4 electron domains which are all single bonds without any lone pairs, the molecular geometry is tetrahedral.
How many pi bonds in BCl3?
BCl3 has no pi bonds. It consists of three sigma bonds formed between boron and each chlorine atom, resulting in a trigonal planar molecular geometry.
Describe the role of each of the following in predicting molecular geometries a unshared electron pairs by double bonds?
In predicting molecular geometries, unshared electron pairs and double bonds influence the overall shape of a molecule. Unshared electron pairs tend to repel bonding pairs, causing distortions in the molecular geometry. Double bonds restrict rotation around the bond axis, affecting the spatial arrangement of the surrounding atoms and leading to a fixed geometry for the molecule.
What is the molecular shape of 2 double bonds?
The molecular shape of a molecule with two double bonds typically depends on the arrangement of the atoms around the central atom. If the double bonds are to two different atoms, the shape is usually planar due to the sp² hybridization, leading to a trigonal planar geometry. However, if both double bonds are to the same central atom, the geometry can be linear if the central atom is bonded to two groups, or it may adopt a different shape based on additional substituents. In general, the presence of double bonds influences the overall molecular geometry by affecting bond angles and spatial arrangement.
What is the molecular geometry of XeO2Cl2?
The molecular geometry of XeO2Cl2 is square planar. This is because the central xenon atom is surrounded by two oxygen atoms and two chlorine atoms, resulting in a symmetrical arrangement with a bond angle of 90 degrees. The lone pairs on the xenon atom are located in the axial positions, giving it a square planar geometry.
