How many lone pair and bonding pair in phosphine?
3 bond pairs and no lone pairs
Lewis Structure for ClF?
14 ve- so 7 bonds/lone pairs. Cl will have three sets of lone pairs on it and F will have three sets of lone pairs on it. There is a single bond between Cl and F 1 bond, 6 lone pairs = total number of ve-
How do you find lone pairs?
one can find the bond pairs by finding the oxidation state on the central atom
What is the bond angle of ICl2-?
The bond angle is 180 because ICl2- has three Lone Pairs attached to it making it Linear.
How does molecular shape effect polarity?
The molecular geometry of a compound helps to determine polarity because, it indicates the number of lone pairs on a central atom thus giving it specified angles and polarity (only if there are lone pairs because if there are no lone pairs on the central atom, them it is non-polar).
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.
How many lone pair and bonding pair in phosphine?
3 bond pairs and no lone pairs
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 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.
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
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?
