Question

Which of the following are considered strong bases? That is, they are capable of doing E2 reactions. (choose all that apply)

Hydroxide, OH-
Ammonia, NH3
Water, H20
ОMethanol, Снзон
Methoxide, CH30-
Cyanide, CN-
Amide, NH2-

Answer 1

CH3O- , OH-, NH-2

Step-by-step explanation:

The given nucleophilic compounds:

Hydroxide, OH-, Ammonia, NH3, Water, H2O, Methanol, CH3OH, Methoxide, CH3O-, Cyanide, CN-, Amide, NH2-

Nucleophile capable for doing E2reaction:

Generally strong basic compounds are used for E2- Elimination. Because in E2 - elimination proton abstraction and leaving group leaving happen on same time so we need strong base for E2-elimination.

In the given compounds only CH3O- , OH-, NH-2, are strong basic compounds so these compounds only capable for doing E2-Elimination.
