  • 2. 

    An isomer is a molecule with the same?

    • Molecular formula

    • Physical properties

    • Chemical properties

    • None of the above

    Correct Answer
    A. Molecular formula
    Explanation
    Isomers are molecules that have the same molecular formula but different structural arrangements. This means that they have the same number and types of atoms but are arranged differently in space. Isomers can have different physical and chemical properties due to their different structures, which can affect their reactivity, boiling points, melting points, and other properties. Therefore, the correct answer is "Molecular formula".

    Rate this question:

  • 3. 

    What is another name for structural isomers?

    • Constitutional isomers

    • IUPAC

    • Proton

    • None of the above

    Correct Answer
    A. Constitutional isomers
    Explanation
    Structural isomers are compounds that have the same molecular formula but differ in the arrangement of atoms within the molecule. They have different connectivity of atoms and thus different chemical properties. The term "constitutional isomers" is commonly used to describe structural isomers. Therefore, the correct answer is "Constitutional isomers".

    Rate this question:

  • 4. 

    In chain isomerism, hydrocarbon chains have variable amounts of?

    • Molecule

    • Atom

    • Electron

    • Branching

    Correct Answer
    A. Branching
    Explanation
    In chain isomerism, hydrocarbon chains can have different amounts of branching. This means that the carbon atoms in the chain can be arranged in a straight line or they can have branches or side chains attached to them. The presence or absence of branching affects the physical and chemical properties of the hydrocarbon, making it an important factor to consider in organic chemistry.

    Rate this question:

  • 5. 

    Isomers contain the same number of atoms of?

    • Each element

    • Compound

    • Proton

    • Electron

    Correct Answer
    A. Each element
    Explanation
    Isomers are molecules that have the same molecular formula but different structural arrangements. This means that they contain the same number of atoms of each element. Therefore, the correct answer is "Each element".

    Rate this question:

  • 6. 

    Position isomerism deals with the position of a functional group on a?

    • Molecule

    • Mass

    • Matter

    • Chain

    Correct Answer
    A. Chain
    Explanation
    Position isomerism refers to the arrangement of functional groups on a carbon chain. In this type of isomerism, the functional group is located at different positions along the carbon chain, resulting in different chemical properties. Therefore, the correct answer is "Chain."

    Rate this question:

  • 7. 

    Structural isomers have different IUPAC names and may or may not belong to the same?

    • Family

    • Functional group

    • Compound

    • None of the above

    Correct Answer
    A. Functional group
    Explanation
    Structural isomers have the same molecular formula but different structural arrangements. They can have different functional groups, which are specific groups of atoms that determine the chemical behavior of a compound. Therefore, the statement that "Structural isomers have different IUPAC names and may or may not belong to the same functional group" is correct.

    Rate this question:

  • 8. 

    A two position isomer would be 2-fluoropropane and?

    • 1-fluoropropane

    • 3-fluoropropane

    • 4-fluoropropane

    • 0-fluoropropane

    Correct Answer
    A. 1-fluoropropane
    Explanation
    An isomer is a compound with the same molecular formula but different structural arrangements. For fluoropropane, the fluorine atom can be attached to different positions on the propane chain. The two position isomers for fluoropropane are 2-fluoropropane and 1-fluoropropane. There is no 3-fluoropropane, 4-fluoropropane, or 0-fluoropropane because in a three-carbon chain like propane, fluorine can only be attached to the first or second carbon to create different isomers.

    Rate this question:

  • 9. 

    In functional group isomerism, one functional group is split up into different?

    • Matter

    • Object

    • Ones

    • None of the above

    Correct Answer
    A. Ones
    Explanation
    In functional group isomerism, one functional group is split up into different "ones". This means that the original functional group is divided or rearranged to form multiple different functional groups. This phenomenon occurs when the atoms within the functional group are rearranged or connected in a different way, resulting in different chemical properties and reactivity. Therefore, the correct answer is "Ones".

    Rate this question:

  • 10. 

    In skeletal isomers, the main carbon chain is different between the two?

    • Compound

    • Forms

    • Molecules

    • Isomers

    Correct Answer
    A. Isomers
    Explanation
    Skeletal isomers are a type of isomer where the main carbon chain differs between the two molecules. This means that the arrangement of carbon atoms in the backbone of the molecules is different, resulting in different chemical properties and structural characteristics. Isomers, in general, are compounds that have the same molecular formula but different structural arrangements, and skeleton isomers specifically refer to isomers with differing main carbon chains.
