What are the products of the following reaction: #CH_3-C(CH_3)=CH-CH_3 + HBr #? Is it antimarkovnikov?

Answer 1

Ruby Allen

Antimarkovnikov is the outcome if hydrogen peroxide and HBr are present in the reaction.

Please double-check your question; it's possible that you left out the peroxide.

Lucy Alessi

The products of the reaction are 2-bromo-2-methylbutane and hydrogen bromide. This reaction follows Markovnikov's rule, not anti-Markovnikov, as the hydrogen atom adds to the carbon atom with more hydrogen atoms attached (secondary carbon), leading to the formation of the more stable carbocation intermediate.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
