<span>Mnemonics for Functional Groups
These are possible mnemonics for the common functional groups.
Vowels: The vowels "A", "E", and "Y" for Alkane, Alkene, and Alkyne.
Remember there is no "I." "O" and "U" would result in awkward pronunciations.
Alcohol: Look for the "C-O-H" in "Alcohol."
Ether: Ethers were anesthetics used in the 1800s.
Dr. Kellogg also lived at the same time. Corn Flakes are made by Kellogg's. A rooster or wingspan (C-O-C) is the cornflake mascot.
Amine: Remember the "N" stands for nitrogen.
Aldehyde: This sounds like "Adelaide," the Australian city.
Australia is at the end of the Asian islands, and aldehydes are at the end of the hydrocarbon chain. The "Y" indicates a C=O double bond.
Ketone: Imagine the diagonal strokes of "K" forming the C=O double bond.
Carboxylic Acid: "Box" stands for boxed wine or C-O-H, alcohol. The "Y" indicates a C=O double bond.
Ester: This sounds like "Estelle" George Costanza's mother in the TV show Seinfeld. George's nickname was Koko or Coco. So think of O=C-O-C.
Amide: Amine with a "D". D for double.</span>
D = m / V
11.3 = 282.5 / V
V = 282.5 / 11.3
V = 25 cm³
Answer C
