Alcohol Isomers of 1-Butanol

Which of the following compounds is considered an isomer for 1-butanol?

F-C-C-C

Answer:

None of the given options are alcohol isomers of 1-butanol as they do not possess the alcohol functional group and some have different molecular formulas. However, 2-butanal has the same molecular formula and is a structural isomer.

When determining isomers of 1-butanol, it is important to look for compounds with the same molecular formula but different arrangements of atoms. In this case, none of the options provided - ethyl methyl ether, dimethyl ether, and diethyl ether - are isomers of 1-butanol that belong to the alcohol functional group.

2-butanal, on the other hand, has the same molecular formula (C4H10O) as 1-butanol but is a structural isomer as it is an aldehyde rather than an alcohol. While not fitting the criteria for an alcohol isomer, 2-butanal does demonstrate a different arrangement of atoms, making it the closest structural isomer to 1-butanol based on the options provided.
