Chapter 16—Aldehydes and Ketones 16.1 Structure and Bonding Methanal (always called formaldehyde) has a carbonyl group that is bonded to 2 hydrogen atoms. Ketone—carbonyl group bonded to 2 carbon atoms. o Propanone (Acetone) 16.2 Nomenclature Follows familiar pattern of selecting the parent alkane the longest chain of carbon atoms that contains the functional group. Aldehydes change the suffix –e to parent alkane to –al. For cyclic molecules in which –CHO is bonded directly to the ring, the molecule is named by adding the suffix –carbaldehyde to the name of the ring.

Unformatted text preview: (Cyclopentane-carbaldehyde) The parent chain is numbered from the direction that gives the carbonyl carbon the smaller number. When naming compounds that contain more than one functional group that be indicated by a suffix, the IUPAC system has established an order of precedence of functions. 16.3 Physical Properties Diethyl Ether is a polar molecule, but because of steric hindrance, only weak dipole-dipole interactions exist between its molecules....
