Final answer:
Elimination/condensation reactions are most likely to occur in aprotic solvents and basic conditions. The options (b) and (d) are correct.
Step-by-step explanation:
Elimination/condensation reactions are most likely to occur under the conditions of:
- aprotic solvent
- basic conditions
These conditions promote the formation of double or triple bonds and the removal of small molecules like water. For example, in the presence of a polar aprotic solvent and a strong base, elimination reactions like E1 and E2 can occur, leading to the removal of a leaving group and the formation of a double or triple bond. Therefore, options (b) and (d) are correct.
