Which among the following is not a base ?a)NaOHb)KOHc)NH4OHd)C2H5OHCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

C₂H₅OH (ethyl alcohol) does not dissociate into OH^- ions on dissolving in water.

Answer

Yes, the answer is Option (d) C2H5OH. Because, as per the option a,b and c, these are all the bases. But in Option d, C2H5OH is Ethanol which having a functional group Alcohol (-OH), is not actually a base. So, option d is correct Friend.

Answer

..C2H5OH..IS ethanol....
it has ph something 7....

Answer

Answer = d
Ethanol, a volatile, flammable, colorless liquid with the molecularformula of C2H5OH, is most commonly known as alcohol. Ethanol can be oxidized to acetaldehyde, and can be further oxidized to acetic acid.

Answer

C2 H5 OH is Methenol and since it consists of  two carbon 5 hydogen and alcohol .Alcohal i.e. OH belongs to the functional group on which the compounds chemical nature depends .Alcohol is acidic in nature therefore option D methenol is the correct answer  It is acidic in nature

Answer

C2H50H

Answer

Explanation:

Definition of a Base:
A base is a substance that can accept a proton (H+) or donate a pair of electrons. It is characterized by its ability to neutralize an acid and form a salt. In other words, a base is a substance that increases the concentration of hydroxide ions (OH-) in a solution.

Analysis of the Options:
a) NaOH (Sodium Hydroxide):
Sodium hydroxide is a strong base. It dissociates completely in water to produce sodium ions (Na+) and hydroxide ions (OH-). Therefore, NaOH is a base.

b) KOH (Potassium Hydroxide):
Potassium hydroxide is also a strong base. Like NaOH, it also dissociates completely in water to produce potassium ions (K+) and hydroxide ions (OH-). Hence, KOH is a base.

c) NH4OH (Ammonium Hydroxide):
Ammonium hydroxide is a weak base. It is a solution of ammonia (NH3) in water. In water, ammonia reacts with water molecules to produce ammonium ions (NH4+) and hydroxide ions (OH-). Therefore, NH4OH is a base.

d) C2H5OH (Ethanol):
Ethanol is not a base. It is an organic compound belonging to the alcohol family. It does not have the ability to accept a proton or donate a pair of electrons. Ethanol is a neutral compound and not classified as an acid or a base.

Summary:
Among the given options, NaOH, KOH, and NH4OH are all bases. However, C2H5OH (ethanol) is not a base. It is important to note that while the other options are all hydroxides, which are generally bases, ethanol does not possess the necessary properties to be classified as a base.
