Question
Chapter 6.3, Problem 6.3P
Interpretation Introduction
Interpretation:
The carbocations should be arranged in increasing stability order.
Concept Introduction:
Carbocation: The carbon ion that bears a positive charge on it is termed as carbocation.
Carbocation stability order:
The tertiary carbocation is more stable than secondary and primary since tertiary carbocation contains 3 methyl groups (electron releasing) in which the positive charge is distributed. The more positive charge gets distributed, more stable the compound. Therefore, the tertiary is more stable than secondary and secondary is more stable than primary.
