Acetaminophen, or paracetamol, is a convenient structure for practicing the conversion of a line-angle structure to a Lewis dot structure.
Structure to structure of lewis dot notation. okay! we have on the screen a i think most countries, they refer to this as paracetamol. lewis structure? and this is an important skill because able to fill those details back in. so let’s number atoms, particularly in this enough of nitrogens and oxygens, we can fill those in later. so let’s start with one, two, three,
Four, five, six. those represent carbon atoms. so let’s number carbon one and two have two bonds between them, so let’s add that. same is well carbon two only has three bonds shown. it needs to have four bonds. so same. it is shown with three bonds. it needs a fourth bond and that’s to a is to oxygen, so let’s draw that in. that’s hydrogen. we’re going to draw that with
A full bond. i’ll just draw that to the have two bonds; it’s only four electrons. we need four more. those are going to ring. carbon 5 is just like 1 – excuse me – number 2 and number 3. it has three so for the lewis structure, we have to show these hydrogens. now carbon 1 is four bonds. nitrogen has a bond to a hydrogen, so show that as a proper long and let’s give them
C’s. (i forgot to give an oxygen. that completes all four bonds to that carbon. and carbon 8 only has have three other bonds. those are to hydrogens, so let’s draw them in now. we lewis structure only has four valence electrons with those two bonds. it needs completed it. so it’s shown in our current lewis structure with only three its valence. and that is the full lewis
Dot structure for acetaminophen. again, quick and simple line-angle structures, but in our minds we need to be able to lone pairs does that atom have? and so practicing these kinds of problems will
