In an E1 mediated elimination reaction, which of the following statement is not true? The reactivity order for alkyl halides (RX) is tertiary > secondary> primary. The rate of reaction = k₁ [alkyl halide] [NaOCH3]. O The rate is dependent on the leaving group. The reaction proceeds through a carbocation intermediate.

Draw the energy diagram of the following reaction (label and draw reactants, intermediates, and products). Label transition state of the rate limiting step and draw the transition state of the rate determining step. Is it a concerted or stepwise reaction? Write the rate law for this reaction. How do we increase the reaction rate? If we use deutrium-tert-butyl bromide such as (CD3)3CBr instead of (CH3)3CBr, will it increase or decrease the reaction rate? Or there is no meaningful rate change. Write reasons for your answer. Draw mechanisms for reactions by drawing arrows and intermediates.

How does gold help to catalyze the reaction in the gold catalysis experiment? It deprotonates the methanol, making methanol a better nucleophile. оа. o b. It donates electron density to the alkyne, making the alkyne a better nucleophile. О с. It coordinates to the methanol, making methanol a better nucleophile. o d. It coordinates to the alkyne, making the alkyne a better electrophile.
