1-propanol to 2-bromopropane organic conversion 1-propanol (propanol) is an alcohol compound and 2-bromopropane is an alkyl halide compound. Both compounds have three carbon atoms. We have to convert propanol to 2-bromopropane. In 2-bromopropane (the IUPAC name), bromine atom is attched to the second carbon atom. The alcohol group is attached to the end of carbon chain of propanol. Also we can write propanolas 1-propanol. In 2-bromopropane, bromine atom is attached to the second carbon atom in the carbon chain. Steps of converting 1-propanol to 2-bromopropane Your target should be to prepare an alkyl halide compound. We have learnt Alkene can be prepared by the reaction of an alcohol compound and dehydrators. These each steps are explained in detail below. 1-propanol and dehydrators reaction 1-propanol (propanol) reacts with a dehydrator to give propene. Propene is an 2O molecule from a alcohol. When ethene is given, Alcohol group (-OH) of propanol is removed by taking a hydrogen atom which is bonded with next to the -OH bonded carbon atom. • concentrated H 2SO 4 acid with heating • Alumina (Al 2O 3) with heating • P 2O 5 + heating Propene and HBr reaction HBr reacts with propene accoding to the markovnikov rule to give products. In addition of HBr molecule to propene, hydrogen atom is added to the carbon atom which has more hydrogen atoms. Bromine atom is added to the other carbon atom to give 2-bromopropane.

\( \newcommand\) • • • • • • • • • • This page looks at the reactions between halogenoalkanes (haloalkanes or alkyl halides) and hydroxide ions from sodium or potassium hydroxide solution. It covers both substitution and elimination reactions. Substitution reactions In a substitution reaction, the halogen atom is replaced by an -OH group to give an alcohol. For example: Or, as an ionic equation: In the example, 2-bromopropane is converted into propan-2-ol. The halogenoalkane is heated under reflux with a solution of sodium or potassium hydroxide. Heating under reflux means heating with a condenser placed vertically in the flask to prevent loss of volatile substances from the mixture. The solvent is usually a 50/50 mixture of ethanol and water, because everything will dissolve in that. The halogenoalkane is insoluble in water. If you used water alone as the solvent, the halogenoalkane and the sodium hydroxide solution wouldn't mix and the reaction could only happen where the two layers met. Elimination reactions Halogenoalkanes also undergo elimination reactions in the presence of sodium or potassium hydroxide. The 2-bromopropane has reacted to give an alkene - propene. Notice that a hydrogen atom has been removed from one of the end carbon atoms together with the bromine from the centre one. In all simple elimination reactions the things being removed are on adjacent carbon atoms, and a double bond is set up between those carbons. The halogenoalkane is heated under reflux ...
