Write structural formulas for compounds that meet the following descriptions:

d. A disubstituted benzene with a total of 8 carbons (three possibilities)

Accepted Answer

Hi, everyone. Let's take a look at the next question, which of the following structural formulas for compounds does not meet the following description. A mono or die substituted benzene. And we have three different structures A B and C and then a choice D, none of the above. So we'll look at these each one at a time. But first, let's think about what is a mono or dye substitute benzene? We know that a plain benzene ring is that six carbon ring with three double bonds. And, and we look at the basic structure, each of these carbons has a single hydrogen coming from it. So you can substitute these hydrogens with different substituents. So anytime you replace a hydrogen, you would be substituting your benzing rings. So mono or die substituted, would mean that either one or two of the hydrogens of the H atoms were replaced by our groups or I should say group or groups depending on if it's one or two. So put the s in parentheses and don't forget we have that choice. D none of the above. Perhaps all of them are either monitor or die substituted. So let's look at choice a choice A, we have our benzene ring and we see we have an ethel group attached to the top carbon. So that would be our R group, this ethyl group, I'm going to go ahead and highlight it in blue. So we have one, our group replacing one hydrogen. So this would be mono substituted. So choice A is mono substituted. Now, let's look at choice B. In choice B, we can see we have two substituents. Two of our hydrogens have been replaced, we have on carbon one at the top, we have an aldehyde group attached again, one hydrogen replaced at the top. And then in the metas position on carbon three, we have an ethyl group. So a total of two of the original hydrogens around the ring replaced by our groups. So we have our oops, we have R one being our aldehyde group R two being our ethyl group. So in this case, we have a dye substituted benzene ring. So A and B both fit the qualifications. Now, let's look at choice C. Choice C is a bit more complicated. We actually have two benzene rings joined by a bond between two of their carbons. We see some other bonds coming off of the ring, but all of them are hydrogens. So those are not our groups, they are the original hydrogens, one of the hydrogens. And if we look at our say benzene ring on the left and consider our primary benzene ring, one of the hydrogen rings, hydrogen atoms, excuse me has been replaced by a whole benzene ring. So we'd call this a fennel group. So this is indeed mono substituted because the R group is the benzene ring. So we have just one hydrogen replaced by an R group. So we would say that we indeed have a mono substituted benzene ring in choice. C So our answer here will be none of the above because we're asking which one of these does not meet the qualifications, meet the description, but all of them do all of our answer choices A B and C Armana or di substituted. So our answer is choice D see you on the next video.
