Which mechanistic step decides the regiochemistry of the radical-chain chlorination of 2-methylpropane?
  1.protonation step
  2.hydrogen abstraction step
  3.chlorine abstraction step
  4.chloride addition step
  5.initiation step

Question 2

Radical chain chlorination of (2R)-fluorobutane yields 2-chloro-3-fluorobutane as one of the products. Which is the best accounting for the stereochemistry of this product?
  1.two enantiomers in equal amounts
  2.two diastereomers in different amounts
  3.two diastereomers in equal amounts
  4.four stereoisomers, in different amount each
  5.four stereoisomers, with enantiomeric pairs in equal amounts, but diastereomeric pairs in non-equal amounts
