4 bondsangles are 109.5 degrees

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.

I would recommend drawing both molecules to identify the key functional groups and relative sizes of the two molecules before attempting to write an answer. Answer: Ethanol molecules have hydrogen bonding...

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 o...
