 Okay, so let's try this one like we were saying very similar to the last problem Except this is not a ring anymore, right? So we should expect that the Max wavelength would be very similar to it, right, but not the exact same So anyways, here we see we've got the conjugated noncyclic Double-floor diene system. So that's going to start us at 217 nanometers And again, like we're saying it's an additive effect of all of these groups. Okay, so Here it says alkyl groups if they're attached to that double bond we're going to add five Nanometers to it. So there's one two alkyl groups here. So ten nanometers So the only difference is because this is not a ring. That's not an exo cyclic double bond So we don't have the last portion to it So add that to 20 so we should expect this molecule to absorb at 227 Any questions about this? What if we move one of the alkyl groups to the 3-carb? Let's do that in the next problem. Okay?
