Identify whether the given statements are true or false. Statement-I: When two or more compounds differ in the position of substituent atom or functional group on the carbon skeleton, they are called position isomers. Statement-II: Propan-1-ol and Propan-2-ol are examples of position isomers.
Correct Answer: D. Both the statements are true.
Explanation: Statement-I is accurate because position isomers are molecules with the same molecular formula but different locations of functional groups or substituents on the carbon chain. Statement-II is also correct as Propan-1-ol and Propan-2-ol share the formula C3H8O but differ only in the placement of the hydroxyl (-OH) group on the first and second carbon atoms, respectively. Since both statements are factually sound, the correct option is that both statements are true.
