So in this question, cholesterol having formula so that I can write cholesterol having formula c 27 h 46 up. So this is a formula of cholesterol and has following structure that is given. And in this structure we see that each point we alignment represents a carbon atom and most hydrogen atom are not shown. So we draw the complete structure off cholesterol, including complete structure off carbon and hydrogen. So we can wrote the structure. So this is carbon. So this is carbon, sis carbon. This is carbon carbon. So basically we just makes us six member drink like this and then here carbon, this is carbon. Then here, this is carbon. This is carbon like this. So basically, these are the 26 members rings and here we can see O h is attached. And with this there is C H three metal group and now we can further bra structures like this is carbon. And then thesis is carbon. This is carbon and this is carbon and this is carbon. So basically, this is also a six member structure. So 123456 So basically six. Now we can see that this carbon is attached with this carbon. Then this carbon on this and then this. So it is basically 123455 member drinks structured. So if I remember drink. So now this this carbon is attached with another metal group, and this is are linked with carbon. And then this is carbon. This is carbon, this is carbon. And then this is carbon. So here you can see this is material group and this is again C H three that metal group. So this is the structure. So here we can also make C H three. So this is the, uh, structure off college store. Now we can make care one double bond, and now we can, uh, brought the hydrogen atoms. So? So we know that the there will be four bonds to each carbon ETA, so we know that can write. Also, there will be there will be for bonds toe each carbon atoms so we can see that. Yeah, carbon makes two bones, so we can used to hydrogen atom. And here we can also use to hydrogen atom. He had three bones, so we can use one hydrogen atom. And here to hydrogen atom. And for this carbon, we know it makes a 41 So no NATO, uh, at hydrogen. So this is 123 And here we can use one hydrogen atom, and in this case, we can use to hydrogen atom. And for in this case, you can use one hydrogen. And now, in this case, we can see 123 bonds. So it makes one another hydrogen atom. And in this case, we can use to hydrogen atom, in this case again can use to hydrogen atom because it makes a to born. And in this case, uh, no need toe, right, hydrogen. So in this case, we use, uh, one hydrogen atom because it makes a three bonds, and in this case, we can see this five member drink. So this is two hydrogen atoms. This is again two hydrogen atoms, and this is 123 So it makes one more hydrogen atom, and this is no need to a hydrogen in this case. Now, coming toe this. So here we can see one toe, three bones, so make one another hydrogen atom and in this case, makes toe hydrogen atom. So again, This is two hydrogen atoms. Similarly, this is for two hydrogen atom and this weekend use one hydrogenated for this carbon. And then this is CS three and CST. So this is the we can see. This is the structure off cholesterol that is C 27 h 46 or so. This is the cholesterol. So this is a structure of Palestine, so we can count the a number of carbon atom in this structure. So in this first six members and we can see 123456 then 789 10 11 then 12 13 14 15 16 17 18 1920 21 22 23 24 25 26 27. So that when total carbon is 27 Now there is one oxygen atom. So this is you can see only one oxygen atom eso This is one oxygen atom like this and now we can count the hydrogen atom so we can see this is two hydrogen toe for six it and then 3, 11 12 13 14 14 and 2 16. Then 18 2021 than 24 26 28 29 then this is 30 33 25 37. Then this is 40 43 45 46. So 46 hydrogen and one oxygen. So this is the basically ah, structure off. Complete structure off carbon and hydrogen off college stall. So this is a complete structure.
