Treatment of 2-methylpropene with which of the following reaction conditions results in an anti-Markovnikov addition product?
A) dry gaseous HBr with peroxides present
B) BH3-THF, followed by alkaline H2O2
C) aqueous Hg(OAc) 2, followed by alkaline NaBH4
D) dilute H2SO4 and heat
E) both A and B
Anti-Markovnikov Addition
A type of chemical addition reaction where the substituent is added to the less substituted carbon atom in a double bond or alkyne.
Peroxides
Chemical compounds containing an oxygen-oxygen single bond, or the peroxide anion O2^2-. They are often powerful oxidizing agents.

Final Answer :
E
Explanation :
Options A and B both lead to anti-Markovnikov addition products. A involves radical addition facilitated by peroxides, which typically results in anti-Markovnikov orientation. B involves hydroboration-oxidation, which also gives an anti-Markovnikov product by adding hydrogen to the more substituted carbon.
