Final answer:
The compound CH₃CH₂CH₂CH₂CH₂OH is polar due to its hydroxyl group and not considered nonpolar. It is expected to be miscible in water because water is polar and 'like dissolves like'. CH₃ CH₂COOH and C3H6O2 can be structural isomers as they share the same molecular formula but can differ in atom arrangements.
Step-by-step explanation:
The statement that the compound CH₃CH₂CH₂CH₂CH₂OH is considered to be nonpolar is false. This is because the molecule contains a hydroxyl group (-OH) which is polar, making the molecule overall polar due to this functional group, despite the nonpolar hydrocarbon chain. Since water is also polar, the compound is expected to be soluble in water, or miscible, to some extent due to the 'like dissolves like' principle. Therefore, the compound will not dissolve in water purely based on its nonpolar hydrocarbon chain.
Molecules with the formula CH₃ CH₂COOH and C3H6O2 could indeed be structural isomers. This is because they have the same molecular formula but can have different structural arrangements of their atoms, leading to different properties.
