    The stereochemistries of the products of the syn- and anti-additions of HBr to but-2-ene are different. In syn -addition of HBr to an alkene, H and Br add to the same side of the C=C bond. Which one of the following is a contributing factor to the stabilization of a tertiary carbenium ion such as Me 3 C + ? Still, much ink has been spent delineating the differences. The manager’s job is to plan, organize and coordinate. The leader’s job is to inspire and motivate. In his 1989 book “On Becoming a Leader,” Warren Bennis composed a list of the differences: — The manager administers; the leader innovates. The addition reaction takes place across the double bond. The addition follows Markownikoff’s rule. This rule states that the hydrogen atom present in the reagent adds to the carbon atom in the double bond which has more number of hydrogen atoms bonded to it. To identify: The major product formed when hydrogen bromide adds to Methylpropene.

    As an example, pure iron can be produced from iron oxide in a blast furnace by the following reaction: 3 C + 2 Fe 2 O 3 → 4 Fe + 3 CO 2 In this reaction, iron oxide (Fe 2 O 3 ) gives away its oxygen to carbon (C). In chemical terms, the carbon is said to be oxidized because it has gained oxygen.
