Transcribed Image Text:**Question:**
Choose the correct missing reagent/condition for the following reaction.
**Reaction:**
An alkyne attached to a phenyl group (\( \text{C}_6\text{H}_5-C\equiv C- \)) is converted to an aldehyde group (\( \text{C}_6\text{H}_5-CHO \)).
**Options:**
- A. 1. Sia\(_2\)BH, THF 2. H\(_2\)O\(_2\)/-OH
- B. HgSO\(_4\)/H\(_2\)SO\(_4\)/H\(_2\)O
- C. A or B
- D. H\(_3\)O\(^+\)
**Explanation:**
The question asks which reagents or conditions are needed to transform a terminal alkyne to an aldehyde. The arrow in the reaction indicates the transformation of an alkyne to a carbonyl group, specifically an aldehyde, which is located at the end of the carbon chain.
