The textbook appears to go back and forth between the systematic name and common name for both primary and secondary/tertiary amines. However, it seems to use the common name for amines that have multiple of the same substituent. Is this a preference or an indication that both forms can be used interchangeably?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
