Which among the following is not a base NaOH C2H5OH KOH NH4OH?

Explanation: Ethanol(C2H5OH) is not a base. Technically, it is neither an acid nor a base under normal conditions, and can be called amphoteric like water as its pKa value is very near to that of water. Among the others, NaOH and KOH are strong bases and NH4OH is a weak base.

Why is C2H5OH not a base?

(i) Ethanol is not a base because it is not example of an organic compound, which have acidic nature. It does not give OH- ions in the solution. (ii) Ionisation When acid is added to water, the molecules of acid dissociate to form ions.

Is NH4OH not a base?

NH4OH is a base because it is an aqueous solution of ammonia that contains two ions (NH4+ and OH–) and anything that has hydroxide ions in an aqueous solution is considered as the base in nature. Hence, Ammonium hydroxide is considered as a base with a pH lie between 7 to 10.

Is NaOH and KOH base?

Both KOH and NaOH are fully ionic strong bases. At equivalent concentrations, there is no difference in base strength when they exist as a dilute solution.

Which of the following is a base NaOH?

Sodium hydroxide is a strong base because it dissociates completely in an aqueous solution to form sodium cations, Na+, and hydroxide anions, OH−. Sodium hydroxide is completely ionic, containing sodium ions and hydroxide ions.

Which of the following is not a base NaCl Koh?

Answer: (d) NaCl. Thank You!

Which among the following is not a base NaOH?

Answer: (d) C2H5OH A base is a molecule or ion able to accept a hydrogen ion from an acid.

Is nhnh4oh a strong base or a weak base?

NH4OH is a very weak base. C2H5OH is not a base rather it is a weak acid. Due to its strong conjugate base. Hence, the answer is c2h5oh.

Is C2H5OH a base or an acid?

Of all this compounds only NaOH ,KOH and NH4OH are bases . C2H5OH is an organic compound and it behaves partially like acid although it contains OH group.

Which of the following is a strong base with pH above 12?

NaOH, KOH are the two strong bases having ph above 12 . Reason being alkali metals are good bases. NH4OH is a very weak base. C2H5OH is not a base rather it is a weak acid. Due to its strong conjugate base.

Why does nanaoh not dissociate into ionic compounds?

NaOH, KOH and NH4OH all dissociate into OH- ion and corresponding cation. The OH- ion is responsible for them being basic. This does not happen in C2H5OH as it is a covalent compond and so it does not dissociate into ions. Infact C2H5OH is slightly acidic as it dissociates into C2H5O- and H+ to some extenet.
