Question
**Use the table,(my individual results have a green arrow pointing to them), to answer the following question. **
Because alcohol protons are reasonably acidic and easily undergo exchange it is important that the base be matched to the appropriate solvent. Explain why it would be virtually impossible to sort out the factors in question 2, if a reaction were carried out using methanol as the solvent and potassium tert-butoxide as the base.
Question 2: Which factor predominates in each reaction, the size of the base or the stability of the alkenes formed? Explain

If we use pottasium tert. Butoxide as base in alcohalic solvent like methanol it will form an addition product at the beta position of the alkene. Another factor is the sta ility of alkene the formation of carbanion is the key step.stability of the alkene plays the key role.
