Indicate the line-angle structure that corresponds to the condensed structure, HOCH₂C(O)CH(CH₃)₂.

Question

Quizplus · Accepted Answer

The line-angle structure for HOCH₂C(O)CH(CH₃)₂ is a bit tricky but can be divided into smaller molecules to make it easier to draw. Starting from the right end, we have CH(CH₃) which is a methyl group attached to a sulfur atom which is attached to a carbon. This can be drawn as follows: ``` S | CH3-C | S ``` Moving on to the left, we have C(O) which is a carbonyl group. This can be represented as: ``` O // C ``` Next, we have ₂ which is a disulfide bond between two sulfur atoms. This can be drawn as: ``` S-S ``` Moving further left, we have HO which is a hydroxyl group attached to a carbon. This can be drawn as: ``` OH | C ``` Finally, we have ₂ again which is the same disulfide bond as before. Putting all these pieces together, we get the line-angle structure: ``` S | CH3-C-O-C-S-S-S-C-OH | S ``` which corresponds to answer choice A.
