You can think of pi bonds in the terms of pi electrons as well which will become more important in terms of aromaticity.
A Triple bond has 1 sigma bond & 2 pi bonds.
There are 6 electrons in a triple bond; 2 sigma electrons and 4 pi electrons.
The two unhybridized p orbitals on each atom on either side of the triple bond are perpendicular to each other. So, if you are trying to determine the number of pi electrons in an aromatic monocyclic compound and you have an uninterrupted combination of sp & sp2 orbitals (sp3 does not have p orbitals), whenever you come across a triple bond you would add 4 pi electrons and for a double bond you would add 2 pi electrons. The important thing to remember though is if the question asks for the number of electrons delocalized in the ring because of the aforementioned p orbitals in a triple bond being perpendicular only 2 of the 4 available pi electrons would delocalize in the ring. The really dirty trick is that Huckel's rule applies to electrons in the cloud, delocalized electrons.

How many valence electrons occupy sigma bond orbitals an pi bond orbitals in c14h10?
26 sigma 7 pi
How do you predict a sigma or pi bond?
there are as many sigma bonds as bonds (of any kind, simple, double or triple). and there is 1 pi bond for each double bond and 2 pi bonds for each triple bond.
How many bond pair electrons in H2O?
There r 4 bonded electrons in h2o and 4 unpaired electrons
How could you predict the presence of a sigma or pi bond in a molecule?
The presence of a sigma will be centered ( with the shared electrons) between the two atoms, such as in water H2O, the sigma will remain between the water and the hydrogen. It will remain in a bonding orbital between the two, the bonding orbital is the region where bonding electrons are likely to be found. As far a pi bond, you know already that there needs to be sigma in order to have a pi, if you have a double bond you can assume that there is one sigma and one pi, if there is a triple bond, you can assume that there will be one sigma and two pi. That's the best way I can explain it, .
A bond that is not symmetrical along the axis between two atomic nuclei is?
its the pi bond .
Does water have pi bonds?
No, Water does not have a pi bond. The molecular formula of water is H2O in which 2 hydrogen is linked with oxygen. Since hydrogen has only one electron, it can make only sigma bond with oxygen.
How many pi bonds are there in a triple bond?
Two pi bonds and one sigma bond.
How many pi bonds are there in a triple convalent bond?
Two pi bonds and one sigma bond.
How many number of pi bond in propyne?
there are 2 pi bonds and 1 sigma bond in propyne (alkynes)
How many pi bond in so2?
O=O One of these double bonds is a sigma and the other is a pi bond. So, one pi bond is the answer.
How many pi bonds are in C6H8?
3 pi bonds C6H8 has a double and a triple bond in it's Lewis structure - the double bond contains 1 sigma and one pi bond while the triple bond has i sigma and 2 pi bonds
How many valence electrons occupy sigma bond orbitals an pi bond orbitals in c14h10?
26 sigma 7 pi
Is a pi bond or a sigma bond weaker?
A pi bond is weaker than a sigma bond.
How many pi bonds are present in acetylsalicylic acid?
Every double bond has one pi bond and one sigma bond. There are five double bonds in acetylsalicylic acid, so there are five pi bonds.
How do you predict a sigma or pi bond?
there are as many sigma bonds as bonds (of any kind, simple, double or triple). and there is 1 pi bond for each double bond and 2 pi bonds for each triple bond.
How many sigma and pi bonds does CO have?
It has one sigma bond and two pi bonds
Is a pi bond equivalent to a single covalent bond?
Pi bond is present in double bonds.Sigma bond forms a single bond.
