What is a lone pair?
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 the change in bond angle down a group when central atom has lone pair?
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
How many lone pair electrons are in ch2o?
There is 1 lone pair around the central C atom
How many lone pairs of electrons does nitrogen have?
There is one lone pair of electrons on the nitrogen atom.
What is A pair of electrons not involved in bonding called?
Such pairs of electrons are called as lone pairs.

Whuch of the following are classified as an electron group?
Lone-pair electrons, Bonded pairs of electrons
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?
one lone pair of electrons
What is the change in bond angle down a group when central atom has lone pair?
there is repulsion between lone pair and bond pair for example in water molecule oxygen has lone pair which repells the bond pair due to this bond angle decreases simply ddue to repulsion btween lone pair to lone pair or lone pair to bond pair angle varies
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.
What takes up more space a lone pair or a single bond?
A lone pair
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.
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.
