what is number of sigma and pi bond in cacl2
Dear student!
Sigma or pi-bonds are found in covalent compound where the formation of bonds takes place by sharing of electrons and overlapping of orbitals.
But CaCl2 is an ionic compound where the one Ca+2 cation is attached to two Cl- anions remain by electrostatic force of attraction and the bond is formed by complete transfer of electrons between calcium and chlorine atoms.
So, CaCl2 does not have any sigma or pi bonds.
