Question

multiple choice 2 points
which of the following conditions can lead to a compound being achiral despite lacking chiral centers?
the compound is aromatic.
the compound is symmetric.
the compound contains triple bonds.
the compound has an equal number of carbon and hydrogen atoms.

Explanation:

A symmetric compound can be achiral even without chiral centers. Symmetry elements like planes of symmetry can make a molecule superimposable on its mirror - image, which is the definition of an achiral molecule. Aromaticity, triple - bonds, or an equal number of carbon and hydrogen atoms do not directly relate to a molecule being achiral in the absence of chiral centers.

Answer:

B. The compound is symmetric.
