Chapter 6, Problem 6.16P

(a)

Interpretation Introduction

Interpretation:

The given alkenes should be arranged in increasing rate when they react with $HI$. The structural formula for major product obtained has to be indicated.

Concept Introduction:

Carbocation: it is carbon ion that bears a positive charge on it.

Leaving group: it is a fragment that leaves from a substrate with a pair of electrons via heterolytic bond cleavage.

Carbocation stability order:

Resonance stabilization: Due to the delocalization of electrons within the molecule the overall energy becomes lower and makes that molecule more stable.

Nucleophile: Nucleophiles are species that donate an electron pair and are also termed as electron-hating species.

Electrophile: Electrophiles are species that accept an electron pair and are also termed as electron-loving species.
