Question

question
ch₃ch₂ch₂c(o)ch₂ch₃ is called:
select the correct answer below:
4 - hexanal
3 - hexanal
4 - hexanone
3 - hexanone

Explanation:

• The compound has a ketone functional group (\(C = O\)) as it is not an aldehyde (no \(-CHO\) group). So, we can rule out the "anal" (aldehyde - based) names.
• For ketone nomenclature, we count the longest carbon chain. Here, the longest chain has 6 carbons (hex -).
• The ketone group (\(C = O\)) is on the 3rd carbon. So, the name is 3 - hexanone.

Answer:

3 - hexanone
