Pi bond is considered to be more diffused than Sigma bonds because
- Sigma bonds are shorter
- Probability of finding an electron in a Sigma bond is greater on the inter-nuclear axis.

∙ 12y agoSigma bonds are considered direct bonds, while pi bonds are indirect. In sigma bonds, the electrons lie on the internuclear axis, while pi bonds do not. This can be visualized as well. Sigma bonds can be visualized as two spheres overlapping for an s orbital or two dumbbells overlapping for a p orbital. A pi bond can be visualized as two dumbbells from p orbitals, but placed parallel to each other, making only a slight overlap on the two nodes.

∙ 9y agoIt is easier to break down pi bonds because they have less overlap of there orbitals than in sigma bonds. This means that less energy is required to fully separate them.

Why double bond is more reactive then triple bond?
because when there is a double bond, there is a Pi bond involved. and Pi bonds are weaker than sigma bonds (which are in single bonds) WRONG. While it is true that Pi bonds are weaker than Sigma bonds, double bonds (C = C) contain BOTH Pi and Sigma bonds making double bonds stronger than single bonds (which contain only a Sigma bond) overall.
Electrons in bonds remain localized between two atoms Electrons in bonds can become delocalized between more than two atoms?
Electrons in SIGMA bonds remain localized between two atoms, Electrons in PI bonds can become delocalized between more than two atoms?
Does pi bonds form before sigma bonds?
No, when covalent bonds are formed, firstly the bonding orbitals prefer to overlap in linear method in which the highest volume of the overlap, and releases a higher energy, rather than partially overlapping. The linear overlap creates a sigma bond whereas a partial overlap creates a pi bond. Therefore a pi bond never exists without a corresponding sigma bond.
What are bonds where more than one pair of electrons are shared between two atoms?
If two electrons are shared then you have a double bond and with three electrons shared you have a triple bond. There is no other bond that exceeds a triple bond because it will make the atom have more than 8 electrons around it . This will make it unstable.
Are covalent bonds more soluble than ionic bonds?
ionic compounds are more soluble than covalent.
Are sigma bonds more electrophilic than pi bonds?
Sigma and pi bonds are nucleophiles. Pi bonds are more nucleophilic than sigma. Electrphilic is not a term usually associated with either sigma or pi bonds.

Why is triple bond between two nitrogen atoms is stronger than a double bond between two oxygen atoms?
because it takes more energy to break a triple bond than a double bondActually we know that in triple bonding one bond is sigma and other two bonds are pi covalent bonds and sigma bond is more stronger than the pi bonds and as the bond order increases the length shorten and the sigma bond become mora stronger which add to other two pi bonds hence tripple bond is more stronger than double bond.because there is three times the dond

What is the difference between single covalent bonds and multiple covalent bonds?
In a single bond there is only a strong sigma bond on the other hand in multiple bond there is a sigma & one or two pi bond, weaker than sigma, which provied addition reactions in a molecule.
Why do nitrogen molecules have triple bonds where is oxygen molecules have double bonds?
I think of it this way: the more bonds an atom has, the stronger it can hold onto the other atom, and therefore it's able to pull it in real tight - making it short and strong both! :) Here's what my chem book says: ---- * A single bond has a bond order of 1. * a double bond has a bond order of 2. * A triple bond has a bond order of 3. In a given pair of atoms, a higher bond order results in a shorter bond lengthand a higher bond energy. A shorter bond is a stronger bond. *Information from Chapter 9 in Silberberg's CHEMISTRY: The Molecular Nature of Matter and Change. 4 Ed. pp 341 - 342.

What is the difference of a sigma bond and a pi bond?
A sigma bond is the end-to-end overlap of the bonding orbitals, usually hybrid orbitals. The sigma bond is a single bond. A pi bond is the side-to-side overlap of unhybridized p-orbitals. A pi bond, along with a sigma bond form a double bond. sigma bond is used in hybridization but pi bond when dealing with saturated molecules is not used,that is double bonds.The oygen molecule is sp hybridized have you ever reasoned or found out why.

What is Theta Phi Sigma's motto?
Theta Phi Sigma's motto is 'We are birthing more than babies, we are birthing dreams'.
What are Sigma and pi bonds?
sigma bonds and pi bonds are both covalent bonds... sigma bond is present in all uni-covalently bonded atoms/molecules... for double covalent bonds, there will be first one sigma bond and one pi bond..similarly for triple covalent bonds, one sigma bond and the rest two pi bonds. REMEMBER, pi bonds are weaker than sigma bonds, hence all triple bonds and double bonded atoms/molecule can react quite easily with other chemicals since the pi bond(s) can be easily broken (Hope that answered your question) Shawkat
