A,B,D
Key Concept
Structural Isomers
Explanation
Structural isomers have the same molecular formula but different arrangements of atoms. C4H10O can have isomers as alcohols and ethers. Options A, B, and D represent different structural arrangements of C4H10O.
Structure 1: 2-butanol, Structure 2: 1-butanol, Structure 3: diethyl ether
Key Concept
IUPAC Naming
Explanation
The IUPAC names are based on the longest carbon chain, functional groups, and their positions. Structure 1 is 2-butanol due to the OH group on the second carbon. Structure 2 is 1-butanol with the OH group on the first carbon. Structure 3 is diethyl ether, an ether with two ethyl groups.
