Find the highest priority functional group. Determine and name the longest continuous carbon chain that includes this group. •Step 2.
Get PriceThere are four isomeric alcohols because there are four C 4 H 9 – alkyl groups (Section 3.3). The n-butyl and isobutyl groups are primary: the tert-butyl group is tertiary. Only the sec-butyl group provides a secondary alcohol, and only secondary alcohols yield ketones when oxidized. Thus, only 2-butanol (sec-butyl alcohol) yields a ketone.
Get PriceAlkyl groups are often represented using the shorthand 'R' and halogens using the shorthand 'X,' so that the molecule above (a form of butane) would be drawn as follows, where the R represents a butyl group and X represents the chlorine atom in this particular case.
