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-

CH3O-, OH-, NH-2

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.
