Answer: Option (c) is the correct answer.

Explanation:

Metallic character means the level of reactivity of metals. It is known that metals have excess of electrons, therefore, in order to follow octet rule they readily lose electrons to attain stability.

Sodium and potassium are metals and therefore, they have high metallic character.

Whereas silicon is a non-metal and readily reacts with a metal to completely fill its valence shell.

On the other hand, krypton is a noble gas and has completely filled shell. Therefore, it's reactivity will be the least.

Thus, we can conclude that krypton has the least metallic character.

choose any bases that will selectively deprotonate the above acid, that is, any bases that will favor the formation of products.

Zanzabum

In order to deprotonate an acid, we must remove protons in order to achieve a more stable conjugate base. For this example, we can use the relationship between carboxylic acid and hydroxide.

Deprotonation is the removal of a proton from a specific type of acid in reaction to its coming into contact with a strong base. The compound formed from this reaction is known as the conjugate base of that acid. The opposite process is also possible and is when a proton is added to a special kind of base. This is a process referred to as protonation, which forms the conjugate acid of that base.

For the example we have chosen to give, the conjugate base is the carboxylate salt. This would be the compound formed by the deprotonated carboxylic acid. The base in question was strong enough to deprotonate the acid due to the greater stability offered as a conjugated base.
