Which is the fastest halide in a halogenoalkane?
The tertiary halide (2-bromo-2-methylpropane) will form halide ions the fastest and the primary halide (1-bromobutane) the slowest. This is due to the reaction mechanisms which are beyond the IB course knowledge. The halogen atom in the halogenoalkane.
How to make halogenoalkanes in a beaker?
Silver nitrate solution, approximately 0.1 mol dm-3 (dissolve 4.25 g in distilled water and make up to 250 cm3) Stop clock. Tube 3: 1 cm3 ethanol + 2 drops of 1-iodobutane. The tubes were then put into a beaker of water about 50 oC.
Can a halogenoalkane be used as a universal solvent?
Halogenoalkanes are also insoluble in water, making it necessary to use ethanol as a universal solvent to substitute the halide atom with the hydroxyl group. How do 1-chlorobutane, 1-bromobutane, and 1-iodobutane affect the rate of halide ion formation in a substitution reaction with hydroxyl ions?
How are halogenoalkanes divided into three groups?
Halogenoalkanes can be divided into three groups depending on how many alkyl groups the carbon atom holding the halogen is directly attached to. The three haloalkane groups are the following: Tertiary haloalkanes – the carbon atom attached to the halogen atom is attached to three other alkyl groups.
