ANSWER

Because in the zinc electron is removed from 4s^2 configuration (which is in stable state) while in copper it is removed from 4s^1 configuration thus more energy is required for the removal of 4s^2 electron than that of 4s^1.

_____________________________

→ ELECTRONIC CONFIGURATION OF

COPPER:- 1S2 2S2 2P6 3S2 3P6 4S1 3d10

ZINC :- 1S2 2S2 2P6 3S2 3P6 4S2 3d10

now,
as you know

2nd Iionisation means Removal of ion from unipositive atom.

→ electrons are always removed from outermost shell.

→ in case of copper 1st electron removed from 4s and then from 3d

→ to remove electron from 3d high energy required because it is fully filled.

→ in case of zinc, both electron is removed from 4s orbital.

NOTE:- AFTER REMOVING 2 ELECTRONS FROM ZINC IT'S OUTERMOST SHELL CHANGES FROM 4S TO 3d.

BUT , I.P OF REMOVING ELECTRONS FROM FULLY FILLED ORBITALS IS ALWAYS GREATER THEN CHANGE IN SHELL.

hope it helps!!
