Which of the following best describes a trisubstituted cyclohexane compound?

• A. A cyclohexane ring with two substituent groups attached to the same carbon atom
• B. A cyclohexane ring with $3$ different substituent groups attached to $3$ separate carbon atoms
• C. A cyclohexane ring with $6$ substituent groups, one on each carbon atom
• D. A cyclohexane ring with only $1$ substituent group attached

Answer: (B)

Verified step by step guidance

1. Understand the term 'trisubstituted cyclohexane': it means a cyclohexane ring that has three substituent groups attached to it.
2. Recognize that 'trisubstituted' implies three substituents are attached to three different carbon atoms, not multiple substituents on the same carbon.
3. Recall that cyclohexane has six carbon atoms arranged in a ring, each capable of bearing substituents.
4. Eliminate options that describe fewer or more than three substituents or multiple substituents on the same carbon, as these do not fit the definition of trisubstitution.
5. Conclude that the best description is a cyclohexane ring with three different substituent groups attached to three separate carbon atoms.
