Lewis Acid and Base

Q. Consider Lewis structure for hydrogen fluoride (HF). a. If hydrogen fluoride were to behave as an acid (if possible), draw the Lewis structure of its resulting conjugate base. b. Reflecting on your answer for Part A and using the three acid-base models above, would you predict the conjugate base would form? (Does this situation make sense)? c. If hydrogen fluoride were to behave as a base (if possible), draw the Lewis structure of its resulting conjugate acid. d. Reflecting on your answer for Part A and using the three acid-base models above, would you predict the conjugate acid would form? (Does this situation make sense)? e. Considering your responses to Parts B and D, would you predict hydrogen fluoride would behave as an acid, a base, either, or neither? Explain your reasoning.

Q. For the reaction: CH3Br + NH3 a) draw out the Lewis structures for the reactants given b) identify the electrophile (meaning a Lewis acid) and nucleophile (meaning a Lewis base) c) draw the curved arrows that show the direction of electron flow to form the product d) draw the structure of the product(s) you would expect.
