Concept:
Basicity of a compound-
Basicity of a compound-
- It is the ability of a compound to donate its pair of electrons.
The basicity of a compound depends on the-
- The less electronegative element has greater basicity due to the low attraction of electrons.
- The compound having a negative charge will have a greater ability to donate electrons and higher will be the basicity.
- Compounds with positive charges will not be willing to give up electrons and will be the least basic.
- Molecules, where the electron pair is delocalized by resonance, will be less basic.
- Compounds, where more than one donor centres are present, will be highly basic.
Explanation:
- In decreasing order of basicity is LiCH3 > LiNH2 > LiOH > LiF.
- The ions, F−, OH−, NH2− and CH3− are stable ions compared to their conjugate acid.

Explanation:
Basicity of a compound:
- The strength of a base is determined by the ability of the compound to donate a hydroxide ion (OH-) in a solution.
- The more readily a compound donates OH- ions, the stronger the base it is considered to be.
Comparison of the given bases:
- LiOH (Lithium hydroxide): Lithium hydroxide is a strong base, but it is not as strong as some other bases. It readily dissociates into Li+ and OH- ions in solution.
- CH3Li (Methyl lithium): Methyl lithium is a very strong base due to the high reactivity of the methyl group and lithium. It is highly reactive and can donate OH- ions readily.
- LiNH2 (Lithium amide): Lithium amide is a strong base, but not as strong as methyl lithium. It can donate OH- ions in solution.
- LiF (Lithium fluoride): Lithium fluoride is not a strong base as it does not readily donate OH- ions in solution.
Conclusion:
- Among the given options, CH3Li (Methyl lithium) is the strongest base due to its high reactivity and ability to donate OH- ions readily in a solution.
