Anyone can explain why NR3H + is...

Quaternary (4) amine? instead of tertiary?
since 3 R is attached, isn't it suppose to be tertiary amine?

where is that from? destroyer lists NR2H as secondary, so your example i would say is tertiary. and does it have a charge from your source?

Yes, it does have a charge on N, and three carbons are attached to it.
It is from destroyer 2011 version Q#12

I just started yesterday and I am going over the stuffs that I got wrong.
wall1two, when you first started with destroyer, how many did you get right out of 30 Q of Chem sections? I got 17 correct on chem and 16 correct Orgo🙁

I am thinking I should be okay to start practicing with bio and Chem, but I am thinking about memorizing the roadmap first, then go over destroyer... Eventhough I went over Chad's orgo and memorized most of basic reactions, I am still having difficluty. Hm...🙁

Even if it has a charge that shouldn't matter based on the molecular formula given. The convention of naming amines and the like as either primary, secondary, or tertiary is mainly to tell how many carbons are attached to the specified atom.

According to the Destroyer it is 4 amine .... 🙁

according to this it's facebook page it looks like the destroyer made an error

3 carbons attached to N would be tertiary not quaternary. 4 carbons attached = quaternary, but then this molecule would be positively charged.
