After adding 5-8% of acetic acid in water it becomes vinegar and is mostly used as preservatives in pickles. When intermolecular interactions are weak, the number of chemical environments is small, and narrow infrared bands are observed. The range from 2850-3000 cm-1belongs to saturated systems (alkanes, sp3, example 1), while the peaks from 3000-3100 cm-1indicate an unsaturated system (alkenes, sp2,example 2; aromatic ring, example 3,4).
