Does NH2 come before Cl in the order of 'importance' when naming compounds?

[Mr. Study]

Don't you have to add amine to the name if NH2 is present?
eg:
     H \          H     H       / H
     H -    C   - C  - C  - C - H = equals 1-chlorobutylamine?
     Cl/          H     H        \ H

Hopefully I've helpd in some way. :S

yep, they have a higher priority, so when naming 'amine' would be the suffix

eg. if there was both a Cl and an NH2 on a 6 carbon chain, you would name it:

X-chlorohexan-Y-amine
X and Y are the locants of the respective substituents

halogens in general have a low priority compared to other functional groups such as esters, amides, carboxylic acid etc..

Ah, I realize you can write it like that aswell but I have trouble doing it like that. Yours is a really easy way of understanding it!

Thanks so much!
