Would CH3-CH2-CH2-O-CH2-CH2-CH3 be Dipropyl Ether or Propyl Propyl Ether? Thanks for checking.

Yes, that is one of the names for this compound:

Names: 1-propoxypropane; 4-oxaheptane; dipropyl ether; ether, dipropyl; propane, 1-propoxy-; propyl ether

To determine the correct name for the given compound, CH3-CH2-CH2-O-CH2-CH2-CH3, we need to follow the IUPAC nomenclature rules for ethers.

In the IUPAC naming system, ethers are named using the alkyl groups attached to the oxygen atom. In this case, we have two propyl groups (CH3-CH2-CH2-) attached to the oxygen in the middle, which means it is a dipropyl ether.

Therefore, the correct name for the given compound is Dipropyl Ether.
