Interpretation: The given compound that can’t be prepared from an
Concept Introduction:
When sodium cyanide is allowed to react with alkyl halide, halide group is replaced by cyanide group via SN2 nucleophilic substitution reaction. The cyanide group on treatment with lithium aluminum hydride which is a strong reducing agent followed by water work-up, it reduces the cyanide group into methylene primary amine. There is a single carbon skeleton increment in the given compound through this process.
The carboxylic acid is converted into the corresponding chloride using thionyl chloride which is allowed to react with ammonia giving the corresponding amide. The amide group on treatment with lithium aluminum hydride which is a strong reducing agent followed by water work-up, it reduces the amide group into methylene primary amine.
To find: Explain the reason for the given compound that can’t be prepared from an alkyl halide or carboxylic acid which serves as a precursor in the preparation of the given amine
Give the general reaction for amine preparation from alkyl halide or carboxylic acid

In case of aromatic or anti-aromatic, please indicate number of I electrons in the respective systems. (Hint: 1. Not all lone pair electrons were explicitly drawn and you should be able to tell that the bonding electrons and lone pair electrons should reside in which hybridized atomic orbital 2. You should consider ring strain- flexibility and steric repulsion that facilitates adoption of aromaticity or avoidance of anti- aromaticity) H H N N: NH2 N Aromaticity (Circle) Aromatic Aromatic Aromatic Aromatic Aromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic nonaromatic nonaromatic nonaromatic nonaromatic nonaromatic aromatic TT electrons Me H Me Aromaticity (Circle) Aromatic Aromatic Aromatic Aromatic Aromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic Antiaromatic nonaromatic nonaromatic nonaromatic nonaromatic nonaromatic aromatic πT electrons H HH…arrow_forwardA chemistry graduate student is studying the rate of this reaction: 2 HI (g) →H2(g) +12(g) She fills a reaction vessel with HI and measures its concentration as the reaction proceeds: time (minutes) [IH] 0 0.800M 1.0 0.301 M 2.0 0.185 M 3.0 0.134M 4.0 0.105 M Use this data to answer the following questions.
