Which of the following statements is CORRECT? All electrophiles are positively charged species. O All nucleophiles are Lewis bases. All nucleophiles are electron-rich and thus transfer electrons during reactions. All electrophiles are electron- O deficient and thus gain electrons during reactions. O All nucleophiles are negatively charged species.
5. Rank the following in decreasing nucleophile quality (1=strongest)? How many are considered strong nucleophiles? (3pts) We will no lo 6. Do you think it is both a strong nucleophile and a strong base? Why or why not? (2pts) Li
4. Strong bases ionize completely in aqueous solution. Which one is NOT a strong base? NaOH Sr(OH)2 KOH NH3 2. Which species is the strongest acid? H2O H2S H2Se H2Te 1. The pH at the equivalence point of the titration of hydrobromic acid (HBr) solution by sodium hydroxide (NaOH) solution is < 2.00 > 11.00 4.00 < pH < 7.00 7.00
what is solution ? (References) Strong acids and strong bases ionize 100% in aqueous solution - HCl is a strong acid. In solution we write it as H(aq) + Cl(aq). - HF is a weak acid. In solution we write it as HF (aq). - KOH is a strong base. In solution we write it as K (aq) + OH(aq). - NH3 is a weak base. In solution we write it as NH3(aq). Exception: Since Ca(OH)2 is only slightly soluble...
