A lone pair is a pair of electrons in an atom that is not involved in bonding with other atoms. It is often represented as a pair of dots in Lewis structures and can influence the shape and reactivity of molecules.

What is responsible for the bent nature of NH3?

There are 3 bonding pairs of electrons N - H and one lone pair . The repulsion forces between lone pair -lone pair is > lone pair -bond pair > bond pair - bond pair. So the lone pair causes distortion from a perfect tetrahedron


How many lone pair of electrons are there in ammonia?

There are 1 lone pair of electrons in ammonia.


What is the change in bond angle down a group when central atom has lone pair?

The bond angle decreases down a group when the central atom has a lone pair. This is because the lone pair exerts greater repulsion on the bonding pairs, causing them to move closer together, resulting in a smaller bond angle.


What is the difference between lone pair and bonding pair electron?

they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.


Why the repulsion caused by lone pair is greater than bonding pair?

lone pair has more electrons than bond pair


How does a lone pair distort a molecular pair?

A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.


Why the lone pair lone pair repulsion is maximum?

Lone pair-lone pair repulsion is maximum because both lone pairs are localized around the same atom, leading to a strong electrostatic repulsion due to their negative charge densities being in close proximity. This results in a greater repulsion compared to other interactions like lone pair-bonding pair or bonding pair-bonding pair repulsions.


What takes up more space a lone pair or a single bond?

A lone pair


How does a lone pair distort molecular shape?

A lone pair of electrons takes up space despite being very small. Lone pairs have a greater repulsive effect than bonding pairs. This is because there are already other forces needing to be taken into consideration with bond pairs. So to summarize: Lone pair-lone pair repulsion > lone pair-bond pair repulsion > bond pair-bond pair repulsion. This makes the molecular geometry different.

Diffirences of bonded and lone pair electron?

The difference between bonded and lone pair is that a bond pair is composed of two electron that are in a bond whereas lone pair is composed of two electron that is not a bond.
