Which region in the IR spectrum could be used to distinguish between butanoic acid and 2-butanone?
1 answer:
Answer:2500-3300
Explanation:We can distinguish between 2-butanone and butanoic acid by analyzing the spectra .
The structure of the two compounds are slightly different as butanoic acid has an OH group whereas for 2-butanone there is no OH group present.
Please refer the attachments for structure of compounds.
Both the compounds will show carbonyl stretching frequency at around 1700-1750cm^{-1}[/tex] due to the presence of carbonyl group in both the compounds.
A broad intense peak at around 3000 will be observed only for butanoic acid due to the presence of OH group and 2-butanone would not show any broad intense peak at around 3000
.
So by analyzing the IR spectra and identifying the intense broad peak of OH we can easily distinguish between butanoic acid and 2-butanone.
Due to hydrogen bonding in between two carboxylic acid molecules ,peak broadening for OH group in butanoic acid takes place.
Generally the ketones show IR stretching in around 1700-1730cm^{-1}[/tex] due to the presence of carbonyl group.
Generally carboxylic acids show IR stretching for carbonyl group at around 1700-1760cm^{-1}[/tex] and a broad intense peak for OH at around 2500-3000cm^{-1}[/tex].

Answer: Option (C) is the correct answer.
Explanation:
A neutral hydrogen atom is defined as the atom in which electrons are resent in their ground state only.
Basically in a neutral atom electrons are present in their parent shell.
For example, atomic number of hydrogen is 1 and electronic configuration of a neutral atom of hydrogen is .
Hence, it means there is only one electron present in its valence shell. So, in order to attain stability it will readily react with another atom to gain or share an electron.
Thus, we can conclude that the statement it is less chemically reactive than an atom of aluminum (Al), is false.
