What is the name given to the pairs of valence electrons that do not participate in bonding ina diatomic oxygen molecules?
The pairs of valence electrons that do not participate in bonding in a diatomic oxygen molecule are called lone pairs. These pairs of electrons are not involved in forming the double bond between the oxygen atoms in O2.
What factors affect bond angle of a molecule?
The bond angle of a molecule is affected by the repulsion between electron pairs around the central atom. Factors such as the number of electron pairs and the presence of lone pairs can influence the bond angle. Additionally, atomic size and electronegativity of the atoms involved can also affect bond angles.

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 many Number of Lone Pairs of Electrons are in Chlorine?
There are three lone pairs present in chlorine atom
Why do lone pairs reduce bond angles?
Lone pairs reduce bond angles because they occupy more space than bonding pairs of electrons. This increased repulsion from the lone pairs pushes the bonding pairs closer together, resulting in smaller bond angles. Additionally, lone pairs are not involved in bonding interactions, so they exert a stronger repulsive force on adjacent bonding pairs, further distorting the geometry of the molecule.
How does lone pairs 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.
What is the bond angle in a molecule with a bent geometry and two lone pairs?
The bond angle in a molecule with a bent geometry and two lone pairs is approximately 104.5 degrees.
What shape would a molecule with two bond groups and two lone pairs have?
A molecule with two bond groups and two lone pairs would have a bent or angular shape. This geometry arises from the repulsion between the lone pairs, which pushes the bond groups closer together. The bond angle is typically less than 109.5 degrees due to the presence of the lone pairs. An example of this molecular geometry is water (H₂O).
