Question

question
ch₃ch₂ch₂ch₂ch₂cho is called
select the correct answer below:
hexanal.
pentanal.
heptanal.
butanal.

Explanation:

Step1: Determine the number of carbon atoms

The given compound is \(CH_{3}CH_{2}CH_{2}CH_{2}CH_{2}CHO\). Counting the carbon atoms, we have 7 carbon atoms.

Step2: Recall the naming rules for aldehydes

For aldehydes (\(-CHO\) group), the suffix is “-anal”. When there are 7 carbon atoms in the longest chain (including the carbon of the aldehyde group), the prefix for 7 carbons is “hept -”.
So, the name of the compound \(CH_{3}CH_{2}CH_{2}CH_{2}CH_{2}CHO\) is heptanal.

Answer:

heptanal.
