Dimethyl ketone, CH3COCH3, is the simplest ketone and is better known by what common name?
AFormalin
BAcetic acid
CAcetone
DEthylene glycol
Answer & Solution
Correct answer: C. Acetone
1. The text gives the common household name for this simplest ketone, widely known as a nail-polish-remover ingredient.
2. It states: "Dimethyl ketone, CH3COCH3, commonly called acetone, is the simplest ketone."
3. Formalin is a formaldehyde solution, acetic acid is a carboxylic acid (vinegar's acid), and ethylene glycol is an alcohol (antifreeze) -- none is CH3COCH3.
4. So dimethyl ketone's common name is acetone.
