IE1 of Cu (3d10 4s1) is less than that of Zn (3d10 4s2) because it is easy to remove an electron from a half-filled s-orbital as compared to fully-filled s-orbital. However, in case of IE2, the electron is lost from 3d orbital of Cu and 4s orbital of Zn and loss of electron from 4s orbital is easier as compared to fully-filled 3d orbital.
