What is sigma and pi bonds?
Can you explain to me what sigma and pi bonds are?
Sure! Sigma and pi bonds are two types of covalent bonds that can form between atoms in a molecule. A sigma bond is formed by the head-to-head overlapping of two atomic orbitals, while a pi bond is formed by the sideways overlap of two orbitals. Sigma bonds are stronger than pi bonds, and they are always present in all kinds of molecules.
