1.

Answer briefly . Compare the covalency of CuCl and NaCl.

Answer»

Solution :CuCl is more covalent than NaCl . Compared to `NA^(+) (1.13 Å). Cu^(+) (0.6 Å)` is small and have `3s^(2) 3p^(6) 3d^(10)` configuration .
Electronic configuration of `Cu^(+)`
`[AR] 3s^(2) . 3p^(6) . 3d^(10)`
Electronic Conguration of `Na^(+)`
[He] `2s^(2), 2P^(6)`
