Consider the following two statements about structural representations of molecules, and select the CORRECT response.
1) In a ring structure, an unlabeled atom at the angle where two lines join is assumed to be a carbon atom.
2) Unlabeled atoms joined to carbon atoms, which are not directly part of a ring structure, are assumed to be oxygen atoms.

Question

Quizplus · Accepted Answer

In a ring structure, an unlabeled atom at the angle where two lines join is assumed to be a carbon atom. However, there is no assumption made about the identity of unlabeled atoms joined to carbon atoms outside of a ring structure. Therefore, statement 1 is true, but statement 2 is false.
