Why the lone pair-lone pair repulsion is more than bond pair-bond pair?

In bonded pairs of electrons the repulsion of the negative charges is somewhat reduce by the positive charge of the bonded atom's nucleus. Lone pairs do not have this.

Why is the water bond angle 104.5 less than the CH4 bond angle 109.5?
in water there are two bond pairs and two lone pairs where as in CH4 there are are four bond pairs nad no lone pair. in ch4 there is only bond pair to bond pair repulsion but in water there are three types of repulsions, lone to lone (greatest repulsion), lone to bond ( lesser repulsion ) and bond to bond ( the least repulsion) , therefore due to the presence of two lone pairs in water the bond pairs are repelled with greater force and they get compressed, reducing the ideal bond angle from 109.5 to 104.5 on the other hand, ch4 has only bond pairs and they dont repel each other that strongly so its angle is greater n its 109.5..
How does a lone pair distort the 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.
How you get bond angle of a tetrahedral shape molecule which have 1 lone pair?
Tetrahedral bond angle of a molecule which have a lone pair electron is 107, smaller than regular 109.5, due to the repulsion of electrons of lone pair.
What has the strongest repulsion bonding pairs or lone pairs?
Lone pairs typically have the greater repulsion because lone pairs want to be as far apart from one another as possible, even more so than bonding pairs. This is because the lone pairs consist of free-moving electrons.
How does a lone pair distort the molecualr shape?
The lone pair creates repulsion between the molecules attached to it and distorts the shape.
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

Why the repulsion caused by lone pair is greater than bonding pair?
lone pair has more electrons than bond pair

What is the shape of the molecul nitrogen trifluoride?
NF3 has trigonal pyramidal shape. Around nitrogen, there are 1 lone pair electron and 3 bond pair electrons. The lone pair-bond pair electron repulsion is greater than bond pair-bond pair electron repulsion. The angle between N-F bond pairs are 107 degrees
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
Why is the bond angle in a water molecule less than the bond angle methane?
The lone pair - OH bond repulsion in water is greater than the OH bond- OH bond repulsion. In methane all of the bonds are the same so it has perfect tetrahedral symmetry. This is VSEPR theory
What is the name given to the pairs of valence electrons that do not participate in bonding ina diatomic oxygen molecules?
These pairs of electrons are referred to as lone pairs.
