Which of the following is the weakest Lewis base F NH2 CH3 Oh?

Explanation: The weakest Lewis base is Cl-, because it has octet rule.

Is CH3 a stronger base than F?

The lone pairs that are shared with a proton reside on C, N, O, and F. Of these, carbon is the least electronegative (most willing to share electrons), so -CH3 (methide ion) is the strongest base. Fluorine is the most electronegative, so F- (fluoride ion) is the least willing to donate electrons (the weakest base).

Is CH3 a stronger base than NH2?

Since NH2 is most stable so least basic,the C=C is less stable acid(less then NH2) so weak base (after NH2) and C triple bond C is most stable acid so most weak base. CH3 is least acidic so most Basic.

Which is the weakest Lewis acid?

Lewis acid strength depends upon the ease with which it can accept a pair of electrons from the donor. BF3 is the weakest Lewis acid due to back bonding.

Which is the strongest Lewis base?

nitrogen hydride
Hence, nitrogen hydride is the strongest Lewis base. The nitrogen hydride $N{H_3}$ is the strongest Lewis base.

Is oh a stronger base than NH2?

Stronger conjugate acids have weaker conjugate base and vice versa . Therefore, NH2- is a stronger base. OH- is better leaving grp because NH2- is stronger base.

Is CH3 a weak base?

So the conjugate base of CH4, CH3(-) is an extremely strong base.

Is OH a stronger base than NH2?

Which is the weakest base?

Basic character of hydroxides of s-block elements increase with increasing atomic number. However alkaline earth metal hydroxides are less basic than alkali metal hydroxides. Therefore, Li(OH) is the weakest base.

WHY IS F a Lewis base?

Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from water, which is transformed into a hydroxide ion. The bisulfite ion is amphiprotic and can act as an electron donor or acceptor.

Which of the following is the weakest Lewis base?

Lewis Base can be defined as a compound which donates an electron pair. Examples of Lewis Base are OH–, CH3–  etc. Explanation: The weakest Lewis base is Cl-, because it has octet rule. Cl – won’t donate electrons easily. Also, it is the conjugate base of strong acid.

What is the Order of basic strength of NH2 and ch3-ch2?

Decreasing order of basic strength: NH2- >OH- > CH3-CH2- > H-C=C- OH- is a conjugate base of H2O and NH2- is a conjugate base of NH3. H2O is stronger acid than NH3 so OH- is a weaker base than NH2- . CH3-CH2- is an alkane H-C=C- alkyne in alkynes S character is more so acidic nature is more.

Which is more basic CH4 or CH3-?

The CH4 is slight acidic whereas the HF is strong acid. There is a fact that the conjugate base of weak acid is very strong while conjugate base of strong acid is very weak. therefore, (CH3)- is more basic… If u understood, please hit that upvote… Which of the following is the weakest Lewis base, CH3, NH2, OH, or F?

Why is NH2 the least basic of the following compounds?

Basically Basicity is opposite of acidity,and acidity is defined by stability of carb anion. Since NH2 is most stable so least basic,the C=C is less stable acid (less then NH2) so weak base (after NH2) and C triple bond C is most stable acid so most weak base.
