Chapter 5

Question 1

Do carbons with less substituents bond to the less or more electronegative group? (modified markovinkovs rule”

Answer 1

The carbon of the double bond with fewer alkyl substituents becomes bonded to the less electronegative group, and the carbon of the double bond with more alkyl substituents becomes bonded to the more electronegative group

Question 2

What is the first step of every reaction?

Answer 2

The first step of every reaction is the donation of an electron pair from the alkene pi bond, acting as a nucleophile to an electrophilic center.
- electrophilic bonds to less substituted carbon
- nucleophilic atom donats its electrons to a more substituted carbon

Question 3

How are electrons donated from double bond?

Answer 3

electrons from pi bond are donated to a less electronegative atom = electrophilic atom H (which accepts and then releases electrons) in H-Br (Br is then leaving group and only accepts protons)

Question 4

What are the processes of turning alkenes into alcohols called?

Answer 4

Oxymeercuration-reduction
Hydroboration-oxidation
