Re: sigma and pi bonds
A single bond is a sigma bond and every other bond after that is a pi bond. For example, in a double bond, there's one sigma and one pi bond and in a triple bond there's one sigma and two pi bonds.
Re: sigma and pi bonds
The first bond made is always a sigma bond while any other bonds made will be pi. (A double bond consists of one sigma and one pi bond. A triple bond consists of one sigma and two pi bonds)

Re: sigma and pi bonds
Yes. All single bonds are sigma bonds. As you add an extra bond, you add a single pi bond to the sigma bond, so a double bond is sigma and pi and a triple bond is a sigma with 2 pis.

Re: sigma and pi bonds
For single bonds there only exists sigma and then for double and triple there are sigma and pi bonds

Re: sigma and pi bonds
All single bonds are sigma bonds. All double bonds have one pi bond and one sigma bond. All triple bonds have one sigma bond and two pi bonds and so on. Pi bonds do not allow the molecule to rotate as much as sigma bonds do.

Single bonds are all sigma bonds.
Double bonds are all sigma and pi bonds.
Triple bonds are all sigma and 2 pi bonds.

Re: sigma and pi bonds
The first bond is always a sigma bond, all bonds following that would be a pi bond.

Re: sigma and pi bonds
Single bonds will always be a sigma bond. Double bonds will always have one pi and one sigma bond. Lastly, triple bonds will always have 2 pi bonds and one sigma bond.

Re: sigma and pi bonds
Pi bonds prevent the molecule from rotating, is this because it is formed from a double bond (one sigma and one pi)?

Re: sigma and pi bonds
Yes, the first bond would be a sigma bond, followed by a pi bond for each additional bond. For example, for a sp hybridization (triple bond), there would be one sigma bond and two pi bonds (using the two empty 2p orbitals).

Re: sigma and pi bonds
Single bond = 1 sigma bond
Double Bond = 1 sigma bond, 1 pi bond
Triple Bond = 1 sigma bond, 2 pi bonds
Double Bond = 1 sigma bond, 1 pi bond
Triple Bond = 1 sigma bond, 2 pi bonds

Re: sigma and pi bonds
Yes, all single bonds are sigma as single bonds are the weakest and thus have the most room for rotation and movement. Double and triple bonds are stronger and thus resist movement hence making them pi bonds.

Re: sigma and pi bonds
Yes all single bonds are sigma bonds, and double bonds contain one sigma and one pi bond, and a triple bond contains 2 pi bonds and one sigma.

Re: sigma and pi bonds
Yes, sigma bonds are single bonds. Pi bonds are any bonds on top of the first one.

Re: sigma and pi bonds
yes and depending on if it is a double or triple bond, you will have different numbers of pi bonds (1 and 2 respectively)

Re: sigma and pi bonds
Just to clarify what has been said above, single bonds consist of one sigma bond. Double bonds consist of one sigma bond and one pi bond. And triple bonds consist of one sigma bond and two pi bonds. Hope this helps!
Re: sigma and pi bonds
Single bond: 1 sigma
Double bond: 1 sigma 1 pi
Triple bond: 1 sigma 2 pi
Quadruple bond: 1 sigma 2 pi 1 delta
Double bond: 1 sigma 1 pi
Triple bond: 1 sigma 2 pi
Quadruple bond: 1 sigma 2 pi 1 delta

This is so helpful! Thank you!
I attached this example of identifying sigma and pi bonds which I found to be a helpful way of applying the information.

Re: sigma and pi bonds
Yes, you are right. All single bonds are sigma bonds and all double bonds are sigma and pi bonds.
