Hydrogens on the alkene have different reactivity which determines which isomer is favored. Hydrogens attached to carbons, and have a weak bond strength are most reactive therefore are favored during abstraction by chlorine. The chloro substituent has an effect on carbon reactivity due to the chlorine atom being an electron withdrawing substituent. The chlorine

There are several types of titrations: Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant. Redox titrations are based on an oxidation-reduction reaction between the analyte and titrant. Complexometric titrations are based on the formation of a complex between the analyte and the titrant. Ex: the chelating agent EDTA is very commonly used to

Also, we will discover its regiochemistry and stereochemistry. Hydration reaction is a process that gives a alcohol functional group and a hydrogen to a carbon-carbon double bond of an alkene. According to Markovnikov's rule the -OH group will be attached to the most substituted carbon which is a carbon connected to the most branches. As the result, in normal hydration reaction of (+)-α-Pinene, the -OH group will attach the carbon attaching to a methyl group. However, the desired product is (-)-Isopinocampheol, in which the -OH group need to attach to the less substituted carbon instead.
