Question

that contains both aldehydeC-O group fequired for the ethylsubstituent, but not the aldehyde C O groups, so the name is 2-ethyllbutanedial. Notice that di is added to account for the two aldehyde C-O groups, and the "e" in ane is retained. JEHP a plasticizer as well as components of skin moisturizers and sunscreens The fourth molecule is a cyclic aldehyde. Unlike the fanctional groups we have dealt with previously, the carbon of an aldehyde C-O cannot be part of the carbon ring. Rather, it is external to the ring but is attached directly to it. In situations like and li the c this, we apply the following rule: at Naming Cyclic Aldehydes st The name of a cyclic aldehyde takes the form cycloalkanecarbaldehyde. In the case at hand, the cycloalkane ring is a cyclopentane, so the molecule is cyclopentanecarbaldehyde. PROBLEM E.16 Write the IUPAC name for each of the following compounds. Он H,Co.
