Question

HBr addition to CF3-CH=CH2 gives antimarkovnikov's

Answer 1

Hope my answer helps you.

if you are taking in this case peroxide then anti markonikooff rule would apply.

if you are taking only HBr then markonikoff rule.

the answer that I have given is considering you are saying to solve through anti markonikiff that is in presence of peroxide.

Answer 2

The Anti-Markovnikov rule describes regiochemistry where the substituent is bound to the less substituted carbon rather than the more substituted carbon.

Explanation:

• The anti-Markovnikov rule can be shown using the addition of hydrogen bromide to isobutylene in the presence of benzoyl peroxide or hydrogen peroxide.
• The reaction of HBr with substituted alkanes was the prototype in the study of free-radical additions.
• The reason for the anti-Markovnikov addition is because it is the Br (bromine) atom that attacks the alkene.
• It attacks the C (carbon) atom along with the most H (hydrogen) atoms.
• So H gets added to C atom with less number of H atoms.
