What is the Ka of aniline?
What is the Ka of aniline?
Kb values for some common bases
| Name | Formula | Kb |
|---|---|---|
| aniline | C6H5NH2 | 4.3 × 10-10 |
| dimethylamine | (CH3)2NH | 5.4 × 10-4 |
| ethylamine | C2H5NH2 | 5.6 × 10-4 |
| hydrazine | NH2NH2 | 1.7 × 10-6 |
Is C6H5NH3 an acid or base?
Aniline hydrochloride, (C6H5NH3)Cl, is a weak acid. Relevance. The acid can be titrated with a strong base such as NaOH. 1 Answer.
Is C6H5COO an acid or base?
(a) The ions are K+ and ClO4-, which come from a strong base (KOH) and a strong acid (HClO4). The salt solution will be neutral. (b) Na+ comes from the strong base NaOH while C6H5COO- is the anion of a weak organic acid. The salt solution will be basic.
What is C6H5NH3Cl?
Aniline hydrochloride, C6H5NH3Cl, is a salt that, after it dissociates in water, has a component that acts as a weak acid (Ka = 2.4 × 10−5 ).
Is KNO2 an acid or base?
Potassium nitrite (KNO2) is an extremely weak basic (essentially neutral) compound (based on its pKa).
What type of acid is HF?
Hydrofluoric acid
What is the Ka of HClO2?
The Ka for HClO2 is 1.1 × 10-2.
Is HClO4 stronger than HCl?
HClO4 is a stronger acid than HCl because it dissociates into its constituent ions more readily. Note that strength of an acid is not related to its pH.
Which is strongest acid H2SO4 or HClO4?
oxyacids. …it can be predicted that perchloric acid, HClO4, is a stronger acid than sulfuric acid, H2SO4, which should be a stronger acid than phosphoric acid, H3PO4. For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases.
Which is the most harmful acid?
Hydrofluoric acid (HF)
Which bond is the weakest HBr HCl HF hi?
1 Answer. There is a single covalent bond between hydrogen and the halogen. H−I is both longer and weaker.
Is HBr weak or strong acid?
It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. The issue is similar with bases: a strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base….Learning Objectives.
| Acids | Bases |
|---|---|
| HBr | NaOH |
| HI | KOH |
| HNO 3 | RbOH |
| H 2SO 4 | CsOH |
Why HI is more reactive than HCl?
HI has the lowest bond dissociation energy due to longer bond length that’s why it is most reactive.
Why HCl is less reactive towards alcohol?
Because the chloride ion is a weaker nucleophile than bromide or iodide ions, hydrogen chloride does not react with primary or secondary alcohols unless zinc chloride or a similar Lewis acid is added to the reaction mixture as well.
Which Halogen is most reactive?
Fluorine
Why is tertiary alcohol more reactive?
The tertiary alcohol is more reactive than other alcohols because of the presence of the increased number of alkyl groups. These alkyl group increases the +I effect in the alcohol.
Does more stable mean more reactive?
1. Reactant Stability/Reactivity: The more stable the reactant, the less reactive it will be. In terms of rates, this means that the more stable the reactant, the slower it will react.
Why is tertiary carbocation more reactive?
A tertiary carbocation forms the most quickly because it is the most stable. All carbocations are very reactive, so their relative reactivity doesn’t matter much for the rate of a reaction.
