Question

In the E/Z naming system, how are priorities assigned to substituents on a double bond?
Options
A Alphabetical order
B Atomic number (higher atomic number = higher priority)
Correct Answer
C Molecular weight
D Number of hydrogens
Correct Answer

Option B is the correct answer.

Detailed Explanation

Cahn-Ingold-Prelog rules: the atom directly attached to the double bond with higher atomic number gets higher priority (e.g., Br > Cl > S > O > N > C > H).

Hint

Compare the atoms directly attached to the double bond.
