Question
**Which of the following equations does NOT show the correct main products?**

**a.**

- Reactants: 
  - HO-CH2CH=CH2
  - 1. BH3, THF
  - 2. H2O2/NaOH
- Products: 
  - HO-CH2CH2CH2OH

**b.**

- Reactants:
  - HO-CH2CH=CH2
  - Hg(OAc)2, H2SO4, H2O
- Products: 
  - HO-CH2CHO

**c.**

- Reactants:
  - HO-CH2CH=CH2
  - 1. Hg(OAc)2, H2O
  - 2. NaBH4/NaOH
- Products: 
  - HO-CH2CH2CH2OH

**d.**

- Reactants:
  - HO-CH2CH=CH2
  - 1. BHSia2, THF
  - 2. H2O2/NaOH
- Products: 
  - HO-CH(CH3)CHO

---

For understanding:

- **Option a**: Hydroboration-oxidation results in syn hydration to form a 1,3-diol.
- **Option b**: Oxymercuration-reduction leads to the formation of an aldehyde.
- **Option c**: Oxymercuration-reduction produces a diol, which is correct for similar reactions.
- **Option d**: Hydroboration with BHSia2 forms an aldehyde, indicating a syn addition with rearrangement.

The incorrect main product in this sequence is under option **b**, since typical oxymercuration should lead to a Markovnikov addition of water without further oxidation to an aldehyde.
