Isomerism Questions and Answers
- 1.
An isomer is a molecule with the same?
- A.
Molecular formula
- B.
Physical properties
- C.
Chemical properties
- D.
None of the above
Correct Answer
A. Molecular formulaExplanation
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:

Isomers contain the same number of atoms of?
- A.
Each element
- B.
Compound
- C.
Proton
- D.
Electron
Correct Answer
A. Each elementExplanation
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:

There are two main forms of isomerism, which are?
- A.
Structural isomerism and stereoisomerism
- B.
Stereoisomerism and physical isomerism
- C.
Chemical isomerism and stereoisomerism
- D.
None of the above
Correct Answer
A. Structural isomerism and stereoisomerismExplanation
The correct answer is Structural isomerism and stereoisomerism. Isomerism refers to the phenomenon where compounds have the same molecular formula but different structural arrangements or spatial orientations. Structural isomerism occurs when compounds have the same molecular formula but different connectivity of atoms. Stereoisomerism, on the other hand, occurs when compounds have the same molecular formula and connectivity of atoms, but differ in their spatial arrangement. Therefore, the two main forms of isomerism are structural isomerism and stereoisomerism.Rate this question:

What is another name for structural isomers?
- A.
Constitutional isomers
- B.
IUPAC
- C.
Proton
- D.
None of the above
Correct Answer
A. Constitutional isomersExplanation
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:

Structural isomers have different IUPAC names and may or may not belong to the same?
- A.
Family
- B.
Functional group
- C.
Compound
- D.
None of the above
Correct Answer
B. Functional groupExplanation
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:

In chain isomerism, hydrocarbon chains have variable amounts of?
- A.
Molecule
- B.
Atom
- C.
Electron
- D.
Branching
Correct Answer
D. BranchingExplanation
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:

Position isomerism deals with the position of a functional group on a?
- A.
Molecule
- B.
Mass
- C.
Matter
- D.
Chain
Correct Answer
D. ChainExplanation
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:

In functional group isomerism, one functional group is split up into different?
- A.
Matter
- B.
Object
- C.
Ones
- D.
None of the above
Correct Answer
C. OnesExplanation
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:

A two position isomer would be 2-fluoropropane and?
- A.
1-fluoropropane
- B.
3-fluoropropane
- C.
4-fluoropropane
- D.
0-fluoropropane
Correct Answer
A. 1-fluoropropaneExplanation
The given question asks for a two position isomer of 2-fluoropropane. A two position isomer refers to a compound that has the same molecular formula but a different arrangement of atoms. In this case, 1-fluoropropane is the correct answer because it has the same molecular formula as 2-fluoropropane (C3H7F) but with the fluorine atom attached to the first carbon instead of the second carbon. This creates a different structural arrangement of the molecule, making it a two position isomer.Rate this question:

In skeletal isomers, the main carbon chain is different between the two?
- A.
Compound
- B.
Forms
- C.
Molecules
- D.
Isomers
Correct Answer
D. IsomersExplanation
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.Rate this question:
