# How do you know if lone pairs are axial or equatorial?

## How do you know if lone pairs are axial or equatorial?

If we place the lone pair in the axial position, we have three LP–BP repulsions at 90°. If we place it in the equatorial position, we have two 90° LP–BP repulsions at 90°. There are five groups around the central atom, three bonding pairs and two lone pairs.

What is equatorial and axial bond?

The carbon bond to the non-ring atoms can be either axial or equatorial. Axial bonds are the bonds that form an 90∘ angle with the ring plane whereas equatorial bonds are the bonds that only make a small angle with the plane. Equatorial bonds are either drawn up and out, or down and out.

For which of the following sets of geometry both axial and equatorial positions are present?

Trigonal bipyramidal, pentagonal bipyramidal.

### How many equatorial and axial positions are there in an octahedral geometry?

An equatorial position in an octahedral geometry has 5 neighboring bond pairs/lone pairs ( 3 in the equatorial plane and two in the axial plane ) while an axial position has 4 neighboring bond pairs/lone pairs (4 in the equatorial plane, the other axial position is not a neighboring position).

What is equatorial and axial position?

The key difference between axial and equatorial position is that axial bonds are vertical while equatorial bonds are horizontal. The terms axial and equatorial are important in showing the actual 3D positioning of the chemical bonds in a chair conformation cyclohexane molecule.

Can lone pairs be axial?

When a molecule has 5 electron pairs, 2 of which are lone pairs, the lone pairs reside in the equatorial positions forcing the bonding atoms into a “T-Shaped” molecular geometry. molecular geometry (MG) with both I-I bonds in the axial positions.

#### What is axial equatorial position?

Axial and equatorial are types of bonds found in the chair conformation of cyclohexane. The chair conformation is the most stable conformation of cyclohexane. Axial positions are perpendicular to the plane of the ring and equatorial positions are around the plane of the ring.

What are the different basic molecular shape?

The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

What are the 6 basic molecular shapes?

The 6 basic molecular shapes are linear, trigonal planar, angular (bent), tetrahedral, trigonal pyramidal, and trigonal bipyramidal.

## What is the difference between geometry and shape?

The key difference between shape and geometry of a molecule is that shape of a molecule is the structure of the molecule excluding the lone pair on the central atom whereas the geometry of a molecule describes the arrangement of lone pair and bond pair electrons around the central atom of the molecule.
