Now a means are classified based on how many carbon atoms are bonded to the nitrogen atom. Now, the classifications primary, we show it as one knot. Secondary is two knot, tertiary is three knot with a means we actually get quaternary structures as well. Now, in a Quain. So for not, we no longer call it just an amine, we call it an ammonium ion. Here, we're gonna say for an ammonium ion that's Quain, we're gonna say the nitrogen atom bonds to four carbon atoms and has a plus one charge. Remember when nitrogen makes four bonds, it has a plus one for its formal charge. So let's take a look down here. We're talking about the classifications of our means. So here we're going to say for the first structure, the nitrogen and there's a nitrogen in each just it goes each of our nitrogens. In the first structure, the nitrogen is connected to one carbon directly. So this is a primary a mean for the next one, it's connected to two carbons directly. So this is secondary. Then here it's connected to three carbons directly. So it's tertiary. Then finally, we have our quaternary ammonium ion quinary because the nitrogen is connected to four carbons directly. And it's an ion because it possesses a charge of plus one. Remember when nitrogen makes four bonds, it's going to be plus one for its charge.

Here, it says classify each structure as primary secondary tertiary or a quaternary ammonia. So for the first one nitrogen is directly connected to two carbons. So this would be a secondary Ame for the next one nitrogen is directly connected to just one carbon. So it's a primary, I mean for the next one nitrogen is connected directly to 1234 carbons. So now becomes a quater ammonium ion ion, meaning that it has a charge when nitrogen makes four bonds, it's plus one for its charge. And then finally, in the last one nitrogen is directly connected to three carbons. So it's a tertiary amine and this would be the classifications for each of the means given to us with this. And within this example question.
