CH3CH2CH2OCH2CH2CH2CH3
When you give IUPAC and common name to this, why butane is after propoxy in IUPAC while propyl is after butyl in common name?

Re: CH3CH2CH2OCH2CH2CH2CH3
For propoxybutane, propoxy comes before butane because the functional group is attached to a shorter chain and is treated a substituent. The longest alkane chain forms the root of the name. Hope this helps!
