The largest effect on a neighboring bond angle is typically exerted by lone pairs of electrons. Lone pairs occupy more space than bonding pairs, causing the bonds around them to compress and alter the angles between neighboring bonds. Additionally, the presence of electronegative atoms can also influence bond angles by exerting inductive effects, but the impact of lone pairs is generally more significant in distorting bond angles.
The bond angle is 180 because ICl2- has three Lone Pairs attached to it making it Linear.
When chlorine is bonded to carbon, it typically has three lone pairs of electrons. Chlorine has seven valence electrons, and when it forms a single bond with carbon, it uses one of its electrons for bonding, leaving three lone pairs. Thus, in this scenario, chlorine retains three lone pairs of electrons.

The central nitrogen atom has five outer electrons with an additional electron from each hydrogen atom. This gives a total of eight electrons, or four electron pairs that are arranged tetrahedrally. Three of these electron pairs are used as bond pairs, which leaves one lone pair of electrons. The lone pair of electrons repel more strongly than bond pairs, therefore the bond angle is not 109.5°, as expected for a regular tetrahedral arrangement, but is measured at 107.8°.
The lone pairs in a water molecule cause it to have a bent or angular shape. This shape is due to the repulsion between the lone pairs and the bonded pairs of electrons around the oxygen atom, resulting in a bond angle of approximately 104.5 degrees.
The bond angle in sulfur dichloride (SCl2) is approximately 103 degrees. This angle is slightly less than the typical tetrahedral angle of 109.5 degrees due to the presence of lone pairs of electrons on the sulfur atom, which repel the bonding pairs and compress the bond angle. The molecule has a bent shape, resulting from the two bonded chlorine atoms and the two lone pairs of electrons.
The central atom of this molecule has two lone pairs and four bonded pairs of electrons. Therefore it has the 'square planar' shape.
The bond angle in a molecule with a bent geometry and two lone pairs is approximately 104.5 degrees.
The bond angle of SeO2 is approximately 120 degrees. This is because the molecule follows a trigonal planar molecular geometry, with the lone pairs of electrons repelling the bonding pairs slightly, decreasing the bond angle from the ideal 120 degrees.
The bond angle in TeO2 is approximately 104 degrees. This value is influenced by the repulsion between the lone pairs of electrons on the Te atom and the bonding electrons.
The difference in bond angles between carbon dioxide and water is caused by the arrangement of the atoms and the presence of lone pairs of electrons. In carbon dioxide, the molecule is linear with a bond angle of 180 degrees because there are no lone pairs on the central carbon atom. In water, the molecule is bent with a bond angle of about 104.5 degrees due to the presence of two lone pairs on the central oxygen atom, which repel the bonded pairs and compress the bond angle.
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..
The bond angle of a bent molecule is typically around 104.5 degrees. This angle is a result of the repulsion between the lone pairs and bonded pairs of electrons around the central atom, causing the molecule to adopt a bent shape.
The largest effect on a neighboring bond angle is typically exerted by lone pairs of electrons. Lone pairs occupy more space than bonding pairs, causing the bonds around them to compress and alter the angles between neighboring bonds. Additionally, the presence of electronegative atoms can also influence bond angles by exerting inductive effects, but the impact of lone pairs is generally more significant in distorting bond angles.
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.
Lone-pair electrons, Bonded pairs of electrons
The bond angle of NBr3 is approximately 107 degrees. This is because the nitrogen atom has a lone pair of electrons that repels the bonding electron pairs, reducing the bond angle from the ideal 120 degrees for a trigonal planar arrangement.
