Are all single bonds sigma bonds and double bonds pi and sigma?

Yep! I believe so.

Yes, and there are also two pi bonds and one sigma bond in a triple bond.

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.

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)

yes you are correct

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.

Yes, you are correct.

For single bonds there only exists sigma and then for double and triple there are 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.

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

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.

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

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).

single bond: 1 sigma, 0 pi
double bond: 1 sigma, 1 pi
triple bond: 1 sigma, 2 pi

Single bond = 1 sigma bond
Double Bond = 1 sigma bond, 1 pi bond
Triple Bond = 1 sigma bond, 2 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.

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.

Yes, sigma bonds are single bonds. Pi bonds are any bonds on top of the first one.

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

yea, and a triple bond has one sigma bond and two 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!

Single bond: 1 sigma
Double bond: 1 sigma 1 pi
Triple bond: 1 sigma 2 pi
Quadruple bond: 1 sigma 2 pi 1 delta

That is true! If you haven't seen this video, https://www.youtube.com/watch?v=pT8nrBrTOm4 you should check it out! It's actually really helpful. I look up videos on youtube for most topics! Hope this helps!

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.

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