Question #5f295
1 Answer
Here's what I get.
Explanation:
1) Phenol and hexan-1-ol
Both compounds have
But phenol has unsaturated
Phenol will show characteristic absorptions at
#"3030 cm"^"-1"# ( aromatic#"C-H"# stretch)#"1600 cm"^"-1"# and#"1500 cm"^"-1"# (aromatic#"C=C"# stretch)#"750 cm"^"-1"# and#"700 cm"^"-1"# (aromatic#"C-H"# bend)
(From webbook.nist.gov)
Hexan-1-ol has none of these characteristic absorptions.
2) Hexane and cyclohexane
Here the difference is more subtle: hexane has methyl groups but cyclohexane doesn't.
Thus, we expect to see
The main difference is that
Compare the two spectra. Do you see the extra absorption band at
