Interpretation:
The curved arrow notation is to be drawn for the proton transfer between
Concept introduction:
In a proton transfer reaction, a proton is transferred from a Bronsted–Lowry acid (proton donor) to a Bronsted–Lowry base (proton acceptor) in a single elementary step in which one bond is broken and another is formed simultaneously. The conjugate acid is the species that the base becomes after gaining a proton, and the conjugate base is the species that the acid becomes after losing a proton. The curved arrow notation shows the movement of valence electrons, not atoms. Each double-barbed curved arrow shows the movement of two valence electrons. To represent bond breaking, the tail of the arrow originates from the center of a bond whereas to represent bond formation, the head of arrow points to an atom which forms the new bond, that is,

- For the previous four questions, label each molecule that appears in the question or your answer asstrong acid, strong base, weak acid, or weak base.arrow_forwardHow do you know which is the acid and which is the base in a proton transfer reaction? Give generalizations ?arrow_forwardWhat is the formula of the conjugate of each of the following acid or base? (see attached photo)arrow_forward
- Draw the products of each proton transfer reaction. Label the acid and base in the starting materials, and the conjugate acid and base in the products.arrow_forwardIdentify the conjugate acid/conjugate base pairs for the structure below. See picture attached.arrow_forwardDescribe a molecule that can be a Lewis acid. Answer:arrow_forward

What makes a good Lewis acid or base? I know it is related to LUMO energy. But why?arrow_forwardcomplete a net ionic equation for each proton-transfer reaction using curved arrows to show the flow of electron pairs in each reaction. Label the original acid and its conjugate base; then label the original base and its conjugate acid.arrow_forward
- a. Which of the acids in the table above has the strongest conjugate base? b. What is the structure of the strongest acid in the table above?arrow_forwardWhat is the weaker base, NH3 or NaNH2?arrow_forward1.Draw the conjugate acid with formal charge(s) below. If there are electrons around any of the atoms ignore them for now. The details will be addressed in the next section. 2. Now specify the details of the structure that was drawn.N with three single bonds and 2 electrons around the atom in the base becomes a N atom with (blank) bonds. (Negative Charge, No Charge, Positive Charge) ,and (BLANK) electron(s) around the atom in the conjugate acid.arrow_forward
