All right. Hi, everyone. So this question is asking us what is the correct common name of the given molecule? Option Acess Pentel, option B says Vilde Hyde, option C says pin aldehyde and option C says valor aldehyde. So starting off with the functional group present in this compound, I want to draw your attention to the right side of the structure. Given. In this case, we can see that there's a carbon double bonded to an oxygen atom otherwise known as a car bal and attached to the car bono carbon is a hydrogen atom. This indicates that the compound in question is going to be an aldehyde and recall that when it comes to an aldehyde, specifically a common way we can differentiate between a common name and an Iupac name is by looking at the suffix or simply the last part of the name itself because for Iupac names, the suffix used is a modifier A L to indicate that the functional group present is in fact an aldehyde. Whereas when it comes to a common name, instead of going for a simple suffix or a modifier, the name aldehyde or the word aldehyde is simply placed at the end of a common name instead. So for a common name, it's the appropriate prefix followed by the word aldehyde. And because of this, I can actually go ahead and eliminate option A in the multiple choice ping up because the suffix here A L tells me that this is the Iupac name of a given aldehyde, which is not quite what we're looking for. So on to the question of the common name, in this case, it just so happens that we have a simple aldehyde where there are no other substituents aside from the car bottle. So first what I'm going to do here is number, the amount of carbons that I have in this molecule and starting off with the car bono carbon at number one, I can see that I have five total carbons present in this molecule. Now recall that when it comes to Iupac names, the appropriate prefix or beginning part of this compound's name would be Pent or Penan as in P to indicate the five carbons. But when it comes to common names, recall that the prefix can somewhat change. For example, if there's only one carbon present, then the appropriate prefix for the common name is form. If it's two carbons, it's a ce T and if it's five carbons like it is, in this case, five carbons requires the prefix va L er or valor. So now putting everything together, I placed my prefix before the word aldehyde and my common name becomes Valor aldehyde, which is option d in the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.
