a, 
b. 
c. 
검증된 단계별 안내1
Step 1: Understand the concept of cis and trans isomers. Cis isomers have substituents on the same side of a reference plane, while trans isomers have substituents on opposite sides of the reference plane.
Step 2: Analyze structure A. Identify the substituents (Br and NH2) and their positions relative to the cyclohexane ring. Determine if they are on the same side (cis) or opposite sides (trans).
Step 3: Analyze structure B. Identify the substituents (CH3 and OH) and their positions relative to the cyclohexane ring. Determine if they are on the same side (cis) or opposite sides (trans).
Step 4: Analyze structure C. Identify the substituents (OH and NH2) and their positions relative to the cyclohexane ring. Determine if they are on the same side (cis) or opposite sides (trans).
Step 5: Summarize the findings for each structure (A, B, and C) based on the spatial arrangement of the substituents and classify them as cis or trans isomers.

Cis-Trans Isomerism
Cis-trans isomerism is a type of stereoisomerism where compounds have the same molecular formula but differ in the spatial arrangement of atoms. In cis isomers, similar groups are on the same side of a double bond or ring structure, while in trans isomers, they are on opposite sides. This difference can significantly affect the physical and chemical properties of the compounds.

Is the following cyclohexane cis or trans?
Double Bonds and Restricted Rotation
Double bonds create a rigid structure that restricts rotation around the bond, allowing for the existence of cis and trans isomers. In alkenes, the presence of a double bond between carbon atoms prevents the free rotation that is possible in single bonds, leading to distinct geometric configurations. This rigidity is crucial for identifying and classifying isomers.

Priority Rules in Isomer Identification
To determine whether a compound is a cis or trans isomer, priority rules based on the Cahn-Ingold-Prelog system are applied. These rules assign priority to substituents attached to the double-bonded carbons based on atomic number and connectivity. The arrangement of these high-priority groups relative to each other helps classify the isomer as cis or trans.
