Amides have strong resonance stabilization due to delocalization of the lone pair of electrons, making them less available for accepting a proton and hence weak bases. In contrast, imides have less resonance stabilization, leading to a more available lone pair of electrons for protonation, making them comparatively stronger bases than amides.

Is MeOH a strong base?
Methanol (MeOH) is not considered a strong base. It is a weak base compared to other compounds.
What is always true pf a weak base?
A weak base will always partially ionize in solution and generate fewer hydroxide ions compared to a strong base. This means that a weak base will have a lower pH compared to a strong base at the same concentration. Weak bases also have higher Kb values compared to strong bases.
When can a solution of a weak base be more corrosive than a solution of a strong base?
A solution of a weak base can be more corrosive than a solution of a strong base when the weak base is concentrated at a higher pH compared to the strong base. The corrosiveness of a base is dependent on factors such as concentration, pH level, and reactivity with the material being corroded.
What is a base that partly dissociates in solution called?
A base that partly dissociates in solution is called a weak base. This means it only partially ionizes in water, resulting in a lower concentration of hydroxide ions compared to a strong base which fully dissociates.
Is borax a weak base or a strong base?
Borax is a weak base. It dissociates in water to form boric acid and hydroxide ions, but the extent of this dissociation is limited, making it a weak base compared to strong bases like sodium hydroxide.

Why imides are more acidic than amides?
Imides are more acidic than amides because the hydrogen atom in imides is present on a nitrogen atom that is more electronegative than the oxygen atom in amides. This greater electronegativity leads to a more stable conjugate base after deprotonation, making the imide more acidic.
Is MgO a strong base?
Yes. It is. This material has been used widely in catalysis area because of its strong basicity.
What tests could be safely used to distinguish a strong base from a weak base?
One way to distinguish a strong base from a weak base is by observing their properties such as the level of dissociation in water. Strong bases completely dissociate in water to form ions, resulting in a higher conductivity compared to weak bases. Another way is to measure the pH of the solution - strong bases will have a significantly higher pH (above 10) compared to weak bases which will have a pH closer to 7.
Why the carbonate ion is a strong base?
The carbonate ion (CO₃²⁻) is considered a weak base, not a strong base. It can accept a proton (H⁺) from water to form bicarbonate ion (HCO₃⁻), which makes it a weak base compared to strong bases like hydroxide ion (OH⁻) which has a stronger affinity for protons.
Does a strong base dissociate more completely in water then a weak base does?
Yes, a strong base dissociates more completely in water compared to a weak base. Strong bases ionize completely into hydroxide ions and the conjugate acid in water, while weak bases only partially ionize. This difference in dissociation affects the pH and reactivity of the solution.
Which base is strong but never concentrated?
A strong base that is not concentrated is an aqueous solution of a weak base. Weak bases have a lower concentration of hydroxide ions compared to strong bases but can still exhibit some degree of basicity. Examples include ammonia (NH3) and bicarbonate (HCO3-).
Why IR carbonyl stretching frequency for an amide is shifted to lower frequencies compared to the carbonyl base value?
The carbonyl stretching frequency in an amide is lowered compared to the carbonyl base value due to resonance effects from the electron-donating amino group. This resonance delocalizes the electron density of the carbonyl group, weakening the C=O bond and resulting in a lower stretching frequency. Additionally, hydrogen bonding in amides can also contribute to the observed shift to lower frequencies.
