student submitted image, transcription available belowPhenols - the original antiseptic When hydroxyl groups are attached directly to a benzene ring, they are called phenols. Phenol was first used by the British surgeon Joseph Lister as an antiseptic to reduce post-operative infections in the late 1800 's. While alcohols and phenols share many chemical and physical properties, they also have differences. For this class, the main learning objective is to recognize and distinguish alcohols from phenols. Phenols are easy to recognize by the presence of the benzene ring. A benzene ring is a six carbon ring with alternating double and single bonds as shown below. Benzene The benzene ring of phenols is one of the few rings that can be represented with a condensed formula C_(6)H_(5)OH

Benzene phenol The henzene ring of phends is one of the few rings that an be represented with a condensed formula is the condensed formula for phenol. Aldehydes and Ketones \& the Carbonyl Group ( Look at molecules and below and answer the following quesiotns.. Both aldehydes and ketone contain carbonyl groups. The cirhonyl group can be described as a common structural ferture of the aldehyde and ketone functional groups. Aldehydes the carhonyl group is at the end of the arhon chain Ketones: the carbonyl group is NOT at the end of the arbon chain 22. Do both compound contain a arhonyl groupt 23. What is the difference between the carbonyl groups of the two compounds? 24. Name the functional group (aldehyde or ketone) for compounds and in the space provided.
