Consider the structures of the three cyclic carbon compounds A, B and C given below and select the correct option from the following:
Consider the structures of the three cyclic carbon compounds A, B and C given below and select the correct option from the following:
Options
A and C are isomers of hexane and B is benzene.
Marking Scheme
- 1A and C are isomers of hexane and B is benzene.
- 2A is an isomer of hexane, B is benzene and C is an isomer of hexene.
- 3A is a saturated cyclic hydrocarbon and B and C are unsaturated cyclic hydrocarbons.
- 4A is cyclohexane and B and C are the isomers of benzene.
Hint
The student should look for the presence of double bonds in the structures to determine if they are unsaturated. They should also count the number of carbon atoms in each structure to determine if they are isomers of hexane or benzene.
Quick Oral Answer
The structures of A, B, and C are different types of cyclic carbon compounds. A and C are isomers of hexane, while B is benzene. The presence of double bonds in B makes it an unsaturated cyclic hydrocarbon, while A and C are saturated cyclic hydrocarbons.
Analysis & Explanation
The question requires the student to identify the correct option based on the structures of the three cyclic carbon compounds A, B, and C. The student needs to analyze the structures and determine whether they are saturated or unsaturated, and whether they are isomers of hexane or benzene.
Common Mistakes
- 1Confusing the structures of A, B, and C.
- 2Not counting the number of carbon atoms correctly.
- 3Not identifying the presence of double bonds correctly.
Interesting Facts
The structure of benzene was first proposed by Friedrich August Kekulé in 1865.
Benzene is a highly reactive molecule due to the presence of double bonds.
Hexane is a highly flammable liquid used as a solvent and fuel.
