Re: double bonds
A double bond consists of one sigma and one pi bond. (Sigma and pi bonds are different because of the different orientation of the orbitals of the bond.)

Re: double bonds
Not exactly. A pi bond has two electrons that lie on two lobes, one on each side of the internuclear axis, but is still only one bond. P-orbitals in a pi bond overlap in a side by side fashion. A sigma bond results from end-to end overlap (consequently because of this a sigma bond is stronger than a pi bond). There cannot be a pi bond without a sigma bond, but the sigma bond is not part of the pi bond, they are the result of separate overlapping orbitals. A double bond contains one sigma bond and one separate pi bond. A triple bond contains one sigma bond and two pi bonds, so a pi bond could not contain a sigma bond otherwise a triple bond wouldn't be possible

Re: double bonds
A single bond consists of a sigma bond. A double bond consists of a sigma and a pi bond, where the electron density is above and below the internuclear axis

Re: double bonds
Double bonds consist of one pi and one sigma bond because the orientation of a double bond consists of a both a side to side overlap as well as a end-to-end overlap. When you continue to add bonds, you'll add another pi bond since there is now another side-to-side overlap.

Re: double bonds
In a double bond there is one pi bond and one sigma bond. In a triple bond, there is one sigma bond and two pi bonds now due an additional side-to-side overlap.

Re: double bonds
A single bond is a sigma bond, a double bond is one sigma and one pi bond, and a triple bond is one sigma bond and two pi bonds.

Re: double bonds
A sigma bond involves end-to-end overlapping of electron orbitals while pi bond involves overlapping of orbitals sideways. A pi bond does not consist of a sigma bond; a double bond consists of both sigma and pi bonds.

Re: double bonds
Because Pie bonds don't overlap like Sigma bonds, they are weaker than Sigma bonds. That's why double bonds are less than twice as strong as single bond.

Re: double bonds
the pi bond wraps around the sigma bond in a double bond, and can only form when a sigma bond is present, but no, a pi bond is only a pi bond.
