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.
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?
Did I write everything correctly?
You didn't indicate where the NH2 group is attached; i.e., which carbon.
anyone can solve this please ?
The amine produced in the above reaction forms a mixture of two
optical isomers
To provide a full equation for the reaction, we need to understand the process of nucleophilic substitution. In this particular case, 2-iodopentane (reactant) reacts with ammonia (NH3) to form an amine (organic product).
a) The full equation for this reaction can be written as:
2-iodopentane + ammonia → amine + hydrogen iodide
The condensed formula for 2-iodopentane is C5H11I. The condensed formula for ammonia is NH3. The amine product can have different structures depending on the specific conditions, but in general, it can be represented as RNH2, where R is an alkyl or aryl group. Hydrogen iodide (HI) is the byproduct.
b) To name the organic product formed from this reaction, we need more specific information about the alkyl group present in 2-iodopentane. However, we can draw the general structure of the amine product:
H H

H-N-R
Here, R represents the alkyl group attached to the nitrogen atom in the amine. The structure shown above is a simplified representation, as the actual structure can vary depending on the specific alkyl group in 2-iodopentane.
