Question

**Title: Understanding Hydroboration-Oxidation of Alkynes**

**Objective:**
Learn how to draw the structure of the major organic product in a hydroboration-oxidation reaction of an alkyne.

**Starting Material:**
An alkyne is shown with the structure:

HC≡C-CH2-

**Reaction Conditions:**
The reaction involves two steps:
1. **Hydroboration**: Using (Sia)2BH in diglyme solvent. Here, "Sia" refers to "sia"myl, which is sec-isoamyl, also known as 1,2-dimethylpropyl.
2. **Oxidation**: Using H2O2, NaOH, and H2O.

**Instructions:**
Draw the major organic product formed after the hydroboration-oxidation reaction.

**Reaction Explanation:**
- Hydroboration-oxidation of alkynes generally leads to the formation of an aldehyde or ketone.
- The addition of (Sia)2BH across the triple bond is regioselective, leading to anti-Markovnikov addition.
- Subsequent oxidation transforms the organoborane intermediate into a carbonyl compound.

**Task:**
Draw the major organic product based on the information above using the drawing tools provided.

Understanding this reaction helps in synthesizing various aldehydes and ketones efficiently.
