All right. Hi, everyone. So this question is asking us to provide the missing products in the following reaction equation. And here we have two pal amine reacting with water. No notice how first and foremost two pal amine is a neutral amine and neutral amines are characteristically weak basis. So the reaction between a weak base like two py amine here or any neutral amine and water is therefore going to be an acid base reaction. So in this case, we're going to be discussing a proton transfer between the acid, which in this case would be water and the base which is two pencil a me. Now recall first and foremost that in the context of a proton transfer, an acid is a species that donates a proton. So the acid itself loses a proton during this process and the base therefore accept the proton that has been donated by the asset. So when drawing out the products in the reaction equation, the idea is to showcase that transfer of the proton from the acid to the base. So the first thing I would do is draw out the structure of two pencil amine starting off with the five carbon chain here. And then I am going to go ahead and draw the nitrogen. However, because the neutral amine to peny amine was the base. Instead of drawing an H two, I would draw NH three on the product side to showcase that an extra proton has been gained. And similarly, when retrying or rather when drawing out the product of an acid base reaction involving water or the conjugate base of water, then I would go ahead and simply remove one proton from the structure of water leaving me with, oh, but I have something miss it, right? Because I was able to draw out the proton transfer, but I've yet to talk about the charge. So let's do that. Now, generally speaking, the charge of a species can be determined by how many protons have been lost or gained, right? For every one proton that has been gained. Then what happens is that the charge increases by one and if a proton has been lost, then the charge is going to decrease by one. So in this case, right, when considering the, the conjugate acid of two py amine, right, the conjugate acid of two peny amine has gained a proton, which means that the charge must therefore increase from neutral or zero to positive one. And so the conjugate base of water has since lost a proton. And so the charge is going to decrease from zero or neutral, its a negative one. And so my products here, two Pentamine reacts with water as an acid to produce the two pal ammonium ion and hydroxide. And there you have it right. So here are or here is the complete acid base reaction involving two pal amine and water because our amen here is a weak base, right? This reaction does not go to completion, it proceeds as an equilibrium. So with that being said, thank you so much for watching and I hope you found this helpful.
