Q75 · Chemistry
Identify product (A) in the following reaction :
1-[3-(3-acetylcyclohexyl)phenyl]ethan-1-one (a cyclohexane ring bearing a COCH group, attached meta to a benzene ring that bears a COCH group) (A) + 2HO
The figure, described in words
Skeletal structures: diketone (acetyl on cyclohexane, acetyl on meta-position of attached benzene) reduced by Clemmensen; options are the corresponding reduced skeletons.
- 1[structure: same skeleton with CH3 in place of each COCH3 (methyl on cyclohexane, methyl on benzene)]
- 2[structure: same skeleton with ethyl (CH2CH3) in place of each COCH3]Official answer
- 3[structure: same skeleton with CH(OH)CH3 in place of each COCH3]
- 4[structure: same skeleton with CH2OH in place of each COCH3 (drawn as CH2–OH and CH2OH)]
Official answer: option 2 · NTA final answer key
