Question

1. (4 points) a. Name the molecule below and write the name on the line given. b. Write the structure of the molecule named below in the box provided cis-2-bromo-3-methyl-2-butene 2. (6 points) Write the letter corresponding to the molecule that reacts fastest next to the name of the reaction mechanism. nur Y SN²

Can you please answer number 2 and explain how to determine what would react fastest?

Answer 1

Answer SNR - A ^ I) The substrate is small and there is no slexic bindrance present on back side of the Side molecule. Thus attack ok nucleophile easily occurs. Thus due to less steric bindrance in molecwe, it undergoes the SN2 reactica Ez E27 Ho The substrate is more subshtuted cind it gives more subshteted alkene. The more subshteted alkene is more stable. The transition state os reachion is also more subshituted and it is allene like character. Thus Substrate D gives more stable Ts as well a more stable Glkene proclucts it undergoes the fastest E2 reaches SNL The Snl recichira Proceedling through the carbocaho. The more stable carbocahon bormed reacticm fate will be faster. The Substrate D giver more stable carbocation than other substrate. Thus it up fastest sNI reachico ate. Thus it undergoes
