Carbocation is the intermediate formed in SN1 reaction.
So, option 1 and 4 are wrong.
Tertiary carbocation is most stable carbocation. It will be formed after rearrangement.
Primary and secondary carbocation will undergo rearrangement.
Answer: tertiary carbocation

Question 10 3 points Which of the following is FALSE regarding Sn2 reactions? They always occur with the inversion of stereochemistry. They occur in a single, concerted step. Rearrangements can occur due the production of a carbocation intermediate. They are the preferred reaction of primary alkyl halides.

the duulatur nucleophile after rearrangement. This is the pluu If the carbocation Is captured by the is captured by the nucleophile before rearrangement. The product distribution (ratio of products) depends on how fast the rearrangemen how fast the nucleophile attacks the carbocation. If the rearrangement occurs faste the nucleophile, then the rearranged product will predominate. However, if the nu the carbocation faster than rearrangement (if it att Gent Gif it attacks before rearrangement occurs), th arranged product will predominate. In...

Question 2 4 pts E1 and Sn1 reactions can compete. Check all of the reasons why E1 predominates in this week's reaction. Note: this question is graded by Canvas as "right minus wrong", subtracting points for wrong answers. o no good nucleophile is present in solution the E1 product is distilled out of the reaction mixture as it is formed, thus the reaction is driven to completion (Le Chatelier's Principle) the intermediate carbocation is too sterically hindered for substitution to...
