Which of the Following Compounds is Most Basic?
The most basic compound is the one with the lowest pKa value.
The answer might surprise you – it’s actually none of the above! In fact, the most basic compound is water, H2O. This is because water has a very high dielectric constant, meaning that it can easily polarize molecules and ions.
This makes it an excellent solvent for many reactions.
Which Compound is Most Basic
A base is a substance that can accept hydrogen ions. A compound is most basic when it has the ability to donate the greatest number of electrons. The Lewis dot structure for a molecule helps to determine which compound is most basic.
In general, the more electronegative an atom is, the more electrons it will want to hold on to. Therefore, a compound with atoms that are less electronegative will be more willing to give up its electrons and be more basic.

Which Following Compound is Most Basic?
A base is a compound that reacts with an acid to form a salt. There are three types of bases: Arrhenius bases, Brønsted-Lowry bases, and Lewis bases. The Arrhenius definition for a base is a compound that increases the concentration of hydroxide ions (OH-) in water.
The Brønsted-Lowry definition for a base is a compound that donates a proton (H+) to another compound. The Lewis definition for a base is a compound that donates an electron pair to another compound.
Of the three definitions, the Lewis definition is the most general, because it includes both Arrhenius and Brønsted-Lowry bases.
All three definitions include compounds that increase the concentration of OH- ions in water, but the Lewis definition also includes compounds that donate H+ or electrons pairs.
Which of the Following Bases is Most Basic?
There are four main types of bases: Arrhenius, Bronsted-Lowry, Lewis, and Amphoteric. Arrhenius bases are defined as substances that increase the concentration of hydroxide ions in water. Bronsted-Lowry bases are defined as proton (H+) acceptors.
Lewis bases are defined as electron pair donors. Amphoteric compounds can act as both an acid and a base, depending on the surrounding conditions.
This is because they donate electrons to other molecules, which effectively neutralizes any acidic protons present. However, it should be noted that amphoteric compounds can also be quite basic under certain circumstances.
Which Compound Has More Basic Character?
In chemistry, there are many ways to determine the basic character of a given compound. In general, the more electronegative an atom is, the more acidic it will be. The less electronegative an atom is, the more basic it will be.
This is because acids donate protons (H^+) to bases, which in turn accept them.
There are several methods used to measure acidity and basicity. One common method is called the Brønsted-Lowry method, which uses pH values.
A substance with a pH below 7 is considered acidic, while a substance with a pH above 7 is considered basic.
Another common method is called the Lewis method, which uses Electron Transfer Potential (ETP) values. A substance with a negative ETP value is considered acidic, while a substance with a positive ETP value is considered basic.
So, which compound has morebasic character? That depends on which method you use! If you use the Brønsted-Lowry method, then compound B has morebasic character than compound A. However, if you use the Lewismethod then compound A has morebasic character than compound B.
Which of the Following Compound is Expected to Be Most Basic Mcq?
In general, the more electronegative an atom is, the more likely it is to donate electrons. This means that atoms with high electronegativities are more likely to be acidic, while atoms with low electronegativities are more likely to be basic. Therefore, of the four options given, we would expect compound C (carbon) to be the most basic.
Which of the following compounds is most basic?
Conclusion
In order to determine which of the following compounds is most basic, we must first understand what base is. A base is a substance that can accept hydrogen ions from another substance. In other words, it is capable of neutralizing acids.
There are many different types of bases, but in this context, we are specifically interested in organic bases. These are molecules that contain a nitrogen atom with at least one lone pair of electrons.
The first compound is ammonia (NH3). This molecule contains a nitrogen atom with three hydrogen atoms bonded to it. It also has one lone pair of electrons on the nitrogen atom.
This makes it an ideal candidate for being a base. The second compound is water (H2O). Water does not contain any nitrogen atoms, so it cannot be an organic base.
However, it can still serve as a base by accepting hydrogen ions from other substances. The third compound is hydrochloric acid (HCl). This molecule contains chlorine atoms instead of nitrogen atoms.
Therefore, it cannot be an organic base either. However, like water, it can still act as a base by accepting hydrogen ions from other substances. Finally, we have acetic acid (CH3COOH).
This molecule contains a carbonatom bonded to two oxygen atoms and onehydrogen atom . The carbonatom also has two lone pairs of electrons . Although this means that acetic acid cannot directly accept hydrogen ions , it can still function asabase by donating its own hydroxide ion s(OH-)to other substances . Therefore , outof allof thecompounds listed ,acetic acidismostbasic .
