What experimental evidence can you provide that the product isolated is 1-bromobutane?

Boiling point and IR Spectra.

Explanation:

The only thing that can be determined to know that the product formed is 1-Bromobutane are two physical methods. The first one is isolation of the product and testing for boiling point because it is an organic compound. If the observed boiling range is 95 to 97 degree Celsius which is very close to published boiling range (100 to 104 degree Celsius), the product formed is 1-bromobutane.

A more readible method is taking the IR spectra of the compound. The characteristic peaks of the compound will be at 2960.20/cm which is relatively close to 2962/cm.

It all depends what reactants were used for forming 1-Bromobutane as there are number of reactants which can be used to form it.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
