Select the correct statements about prefixes, suffixes and ring compounds.

AAn ester outranks an acyl chloride in the order of seniority.
BAn ether oxygen is always expressed as an alkoxy prefix, never as a suffix.
CThe compound $(CH X_{3}) X_{2} CH - CO - CH X_{3}$ is 3-methylbutan-2-one.
DAn amine outranks an alcohol, so $H X_{2} N - CH X_{2} - CH X_{2} - OH$ is named 2-hydroxyethan-1-amine.

Answer: A, B, C

Ethers have no suffix, so alkoxy is the only form (true). The order is acid > anhydride > ester > acid halide > amide, so ester outranks acyl halide (true).

(CH X_{3}) X_{2} CH - CO - CH X_{3}

: chain C4, ketone at C-2, methyl at C-3 (true). The alcohol outranks the amine, so the compound is 2-aminoethan-1-ol (false).
