### Re: σ bonds

sigma bonds occur when there is an overlap between atomic orbitals. 1 single covalent bond is a sigma bond.

### Re: σ bonds

To add on, a sigma bond is a covalent bond resulting from the formation of a molecular orbital by the end-to-end overlap of atomic orbitals. These overlaps can occur between s-s, p-p, s-p

### Re: σ bonds

Single bond: one sigma bond
Double bond: one sigma and one pi bond
Triple bond: one sigma and two pi bonds

### Re: σ bonds

How come double bonds and triple bonds have pi bonds?

### Re: σ bonds

a sigma bond is when there is one single covalent bond
however, double bonds and triple bonds also have a sigma bond

### Re: σ bonds

Remember how the p-orbitals are oriented: one along the x-axis, one along the y-axis, and one along the z-axis. Because of this orientation, only one of the bonds can overlap the orbitals and be a sigma bond. The other orbitals are side-by-side and therefore form pi bonds.

### Re: σ bonds

sign bonds allow atoms to rotate while pi bonds do not. This is because the end-to-end overlap of the atomic orbitals, while in pi bonds there is a side-by-side orientation

### Re: σ bonds

Also remember that a sigma bond is the strongest type of covalent chemical bond.
