What factors affect bond angle of a molecule?
Type of hybridizationthe number of lone pairs and bond pairs
How many bonding pairs of electrons are there in water?
There are four electrons, which is two pair.
How many tatal lone pairs are present in molecule of KrF2?
3
What is the bond angle of krf4?
The central atom of this molecule has two lone pairs and four bonded pairs of electrons. Therefore it has the 'square planar' shape.
How many bond pairs and lone pairs are present in N2F2?
4 bond pairs (F-N=N-F) plus 3 lone pairs on each fluorine and 1 on each nitrogen:together 8 lone pairs plus 4 bond pairs in both cis- and trans-Dinitrogen difluoride

How many lone pair and bonding pair in phosphine?
3 bond pairs and no lone pairs
What is the bond of AB2E2?
An AB2E2 molecule has two atoms and two lone pairs surrounding the central atom. This is the situation is water. The molecule will have a bent shape and the bond angle will probably as in water (105 0) be less than tetrahedral 109.5 0 )- due to lone pair - bond repulsion.
What is bond between the oxygen atoms of oxygen gas?
O2 Has a Double bond, one sigma and one pi, and each atom has 2 lone pairs.
Why does the presence of lone pairs contribute to the polarity of a water molecule?
How do lone pairs around the central atom affect the polarity of the molecule?
Why is ammonia considered a polar molecule?
Ammonia is a polar molecule because the different electronegativity's of the nitrogen and the hydrogen molecules makes the hydrogen slightly positive and the nitrogen slightly negative. However there are 2 valance electons of the nitrogen atom which are not bonded to anything, which are called lone pairs. The lone pairs means that the ammonia molecule is not symmetrical therefore the electronegativity's do not cancel eachother, creating a polar molecule. ( The reason why the shape is no longer symmetircal is because lone pairs repel more than the bond pairs of the N-H, and essentially the bonding pairs are "squeezed" together, which accounts for the smaller than expected bond angle of 107 degrees)
The correct Lewis structure for a molecule of the compound C2H2 contains?
The correct Lewis structure for a molecule of the compound C2H2 contains an alkyne bond. This is a triple bond between two C atoms. It has a linear bond geometry and no lone pairs.
