Is the atom indicated with an arrow nucleophilic, electrophilic, acidic, more than one of these choices, or none of these choices? (For purposes of this question, acidic is defined as pKa ≤ 25.)Select all that apply. a) nucleophilicb) electrophilicc) acidicd) none of the above

c) acidic

Explanation:

pKa is a value which describes the acidity of a solution. The solution is pKa ≤ 25 which means that the solution is more acidic. The lower value of pKa tells us that the solution is more acidic but when the pKa value of solution increases the acidity of the solution is also decreases. Due to lower value of pKa, the acid in the solution is fully dissociates in water.-5 to 50 is the range of the value of pKa for different solutions.

the answer is true. hope it .
