MEK stands for Methyl Ethyl Ketone.

• A. Methyl Ethyl Ketone
• B. Methylene Ethyl Ketone
• C. Methyl Ethyl Ketoneate
• D. Methoxy Ethyl Ketone

Answer: (A)

MEK is the common abbreviation for methyl ethyl ketone, a four-carbon ketone also known as 2-butanone. The name splits into a methyl group and an ethyl group attached to the carbonyl carbon, which is exactly how this ketone is described in IUPAC-style naming. The other options misstate the functional group or substituents: “Methylene Ethyl Ketone” would imply a methylene linkage that isn’t part of the standard name; “Methyl Ethyl Ketoneate” suggests an ester form, which MEK is not; “Methoxy Ethyl Ketone” would denote an ether-containing compound, not a ketone.
