Name each aldehyde or ketone. b.

Welcome back, everyone name the following molecule. We are given four answer choices in this problem A or methyl, one penno B, two methyl five Penan C or methyl Penan in D 44 dimethyl beats. Now, before we begin, we first want to understand what is the main functional group or the class of this compound. And we clearly notice that there is an ALK group R bonded to cho. So in a general form, we have RCO and we have to recall that this is an aldehyde. Now that we know that we're dealing with an aldehyde, our next step is to identify the longest continuous carbon chain starting with carbon number one being part of the curve B. So we have carbon number one or by carbon number two, we or we can go to the left to get five or down and get five as well. It doesn't matter because there are two equivalent metal groups. Now that we have a five number chain, we can identify our parent. Let's recall that in chemistry, the prefix representing five is tensa. So our parent is Benza. And now it is really important to understand that whenever we have aldehydes. The suffix that we use for our parent is A L. So we're going to use Penan L, right? So now that we have our parent, which is Benson, now we also want to identify any subsidence present and we can see that there is branching at carbon number four and carbon number four contains a methyl group. That's what we have, right? Because there's one implicit carbon with three hygen attached to it. So we have four dash methyl and that's the only substitution that we have. So combining them together, we would have four methyl penan L which essentially corresponds to the answer. Choice. C that's our final answer. Thank you for watching.
