Question

because an achiral molecule is symmetrical, flipping it yields a structurally identical molecule. a flipped chiral molecule, ______ can be compared to a glove that has been turned inside out: it produces a structurally inverted molecule rather than an identical one. which choice completes the text with the most logical transition? choose 1 answer: a in other words, b for example, c by contrast,

Explanation:

The text contrasts achiral and chiral molecules. Achiral molecules are symmetric (flipping gives identical structure), while chiral molecules produce inverted structures when flipped. The blank needs a transition showing this contrast. "By contrast" is the only option that signals a comparison of opposing characteristics.

Answer:

C. by contrast,
