Question

1) An amine is formed when 2-iodopentane is heated with ammonia in a sealed tube. This is a nucleophilic substitution reaction.

a) Provide a full equation (using condensed formula) for this reaction. Name the reactants and the overall products too.

b) Name the organic product formed from this reaction and draw it’s displayed structure.

Answer 1

a)

-----H----I---H---H--H ----------------------------H--NH2-H---H---H
------I----I----I---I----I ------------------------ ------I----I--- -I---I----I
H - C - C - C - C - C - H ----+ NH3 ==> H - C - C - C - C - C - H + NH4I
------I----I----I----I----I ------------------------------I----I----I---I-----I
-----H--H---H----H---H ---------------------------H--H---H----H---H

CH3CH(I)CH2CH2CH3+2NH3-> CH3CH(NH2)CH2CH2CH3 + NH4I
2-iodopentane + ammonia ==> pentylamine + ammonium iodide

b)

-----H--NH2-H---H---H
------I----I--- -I---I----I
H - C - C - C - C - C - H
------I----I----I---I-----I
-----H--H---H----H---H

Is this correct?

Answer 2

Did I write everything correctly?

Answer 3

You didn't indicate where the NH2 group is attached; i.e., which carbon.

Answer 4

anyone can solve this please ?

The amine produced in the above reaction forms a mixture of two
optical isomers
