What is Formaldehyde?
H-(C=O)-H
What is Acetaldehyde?
H3C-(C=O)-H
What is Acetone?
H3C-(C=O)-CH3
What is Acetophenone?
Ph-(C=O)-CH3
What is Benzophenone?
Ph-(C=O)-Ph
What is Benzaldehyde?

What is an Alkanoyl Group? (also called an acyl group)
-(C=O)-R
What are the two suffixes commonly used aldehyde nomenclature? (one short and one long)

What is the suffix for ketones?
-one (to replace an -e suffix)
What is the structure for the common names of ketones?
alkyl alkyl ketone
How are diketones named?
both carbonyls require a location number and change the suffix to Dione
if in.a ring, the -e suffix remains and is immediately before the Dione suffix
How are compounds containing both an aldehyde and a ketone named?
compound is named as an aldehyde and the ketone is named as an oxo substituent
ketone needs location number, aldehyde does not
How are aldehydes and ketones named when there is an OH in the same compound?
the OH is a hydroxy substituent
How are cyanohydrins C(-OH)(≣N) produced?
Add NaCN to an aldehyde or a ketone. The =O is replaced with a -OH and -C(triple bond)N
