What are repelled in VSEPR theory?
Electron pairs
How will electron pairs behave towards one another in VSEPR?
electron pairs move away from each other to more electrostatically balanced positions
Why if CO2 and H2O both have 2 atoms around the central atom are they not the same shape?
Because H2O has electron pairs on the O atom which repel the H atoms more and change it's shape. Their electromagnetic repulsion is stronger than a lone electron and they push the H atoms away
What are postulates of vsepr theory?
1: Both the lone pairs asa well as the bond pairs participate in determining the geometery of the molecules 2: The electron pairs are arranged around the central polyvalent atom so as to remain at a miximum distance apart to avoid repulsions 3: The electron pairs of lone pairs occupy more space then the bond pairs from ncert:- 1)The shape of a molecule depends upon the number of valence shell electron pairs (bonded or nonbonded) around the central atom. 2)Pairs of electrons in the valence shell repel one another since their electron clouds are negatively charged. 3)These pairs of electrons tend to occupy such positions in space that minimise repulsion and thus maximise distance between them. 3)The valence shell is taken as a sphere with the electron pairs localising on the spherical surface at maximum distance from one another. 4)A multiple bond is treated as if it is a single electron pair and the two or three electron pairs of a multiple bond are treated as a single super pair. 5) Where two or more resonance structures can represent a molecule, the VSEPR model is applicable
What effect does a lone electron have on a molecular shape?
The lone pair pushes bonding electron pairs away.
What is the VSEPR theory of CO2?
The VSEPR theory, sometimes pronounced 'vesper', stands for Valence Shell Electron Pair Repulsion. It states that repulsion between the sets of electron bond pairs surrounding an atom in a compound causes these sets to be oriented as far apart as possible, giving the compound a certain shape. "Valence electron pairs will move as far apart from each other as possible."
How many electron groups in co2?
2 electron groups are in CO2. Proof, I got it wrong on a quiz. :(
Why does CO2 have a linear shape instead of a bent shape?
The Carbon has double bonds to each of the oxygen atoms, so it does not have any unshared pairs or electrons. Valence shell electron pair repulsion theory dictates that the electron pairs will be repel, so the farthest apart they can be is 180 degrees apart or linear.
What is the role of unshared electron pairs in predicting molecular geometries?
Lone electron pairs give the geometry a triangular base.
Based on the Lewis structure the total number of unshared electrons pairs or nonbonding domains in the CO2 molecules is?
CO2 does not have unshared pairs of electrons.
How many electron pairs are in CF2Cl2?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

What is the hybridization of iodine?
sp3d hybridization for 5 electron pairs (2 lone pairs and 3 bonded pairs).
What type of electron pairs make a molecule a good donor?
the lone pair on electron like nh3 make molecule good donor.
