Question

Which molecular formula corresponds to this model of a chemical compound? (black = carbon; red = oxygen; white = hydrogen) A ball-and-stick model has two black balls bonded to each other at center, with single-bonded red balls bonded to white balls above left and below right, and double-bonded red balls above right and below left. C2(OH)4 C2H2O4 C2H4O2 C4H2O2

Answer 2

C2H2O4

Step-by-step explanation:

The molecular formula can be derived through the below analysis.

Two black balls (C) bonded to each other at the center = C2

Single-bonded red balls (O) bonded to white balls (H) above left and below right = (OH)2 = O2H2

Double-bonded red balls above right and below left = O2

Adding the three together = C2 + O2H2 + O2 = C2H2O4

The correct answer is C2H2O4
