Answer: -
3-Ethyl-N,N-dimethylbenzamide.
Explanation: -
In the first step the nitrogen lone pair attacks the carbonyl carbon.
Then a OH becomes water molecule by protonation and leaves.
Final step involves proton loss to form amide.
Answer:
M KIO3 = 1.254 mol/L
Explanation:
∴ w KIO3 = 553 g
∴ mm KIO3 = 214.001 g/mol
∴ volumen sln = 2.10 L
⇒ mol KIO3 = (553 g)×(mol/210.001 g) = 2.633 mol
⇒ M KIO3 = (2.633 mol KIO3 / (2.10 L sln)
⇒ M KIO3 = 1.254 mol/L
It is a reaction between an element and a compound that results in a different element and compound
