Question

What is the correct order of stability the following carbocations (more stable of 2) a. 1 2 3 b. 1 3 2 d. 3 2 1 30.) Nucleophilic substitution and elimination reactions often complete with the following would enhance the rate of the E2 reaction the SN2 a. use of a weak nucleophile b. branching bulky substituent at the alpha or beta carbon c. use of a weak base d. All of the above would enhance the E2 rate. 81.) What is the best nucleophile in a substitution reaction at a primary carbon. CII OH H20 NH

Explanation / Answer

29.

Tertiary carbocation is more stable than secondary carbocation which is more stable than primary carbocation.

The carbon atom bearing positive charge is bonded to only one other carbon atom is called primary carbocation.

The carbon atom bearing positive charge is bonded to two other carbon atoms is called secondary carbocation.

The carbon atom bearing positive charge is bonded to three other carbon atoms is called tertiary carbocation.

Structure 1 is primary carbocation, structure 2 is secondary carbocation, and structure 3 is tertiary carbocation.

So, the stability order is 1 < 2 < 3.

Answer: d. 3 > 2 > 1
