Write down the electronic configuration of a copper ion in this complex ion: [Cu(H2O)6]2+

The electronic configuration is 1s2,2s2,2p6,3s2,3p6,3d9 (or [Ar]3d9); as the electronic configuration of the neutral copper is [Ar]3d10,4s1, which is unusual and differs from most transition metal ions.

How would you expect the H-NMR spectrum of ethanol to differ from the H-NMR spectrum of ethane?

First, draw out both molecules as this will make the comparison much easier. Count the number of different hydrogen environments in each molecule to determine the number of H-NMR peaks. Count the number of h...
