Subject: Organic Chemistry · Chapter: Organic Spectroscopy · Topic: IR · Exam: NET DEC 2019 · Marks: 2 · Difficulty: Hard
In IR spectrum, recorded neat, a compound shows a strong and broad band at $3300\,\mathrm{cm^{-1}}$. The band becomes sharp and shifts to $3600\,\mathrm{cm^{-1}}$ when the spectrum is recorded in $\mathrm{CCl_4}$ at high dilution. This proves that the compound has
(a)OH group, which is involved in intra-molecular H-bonding
(b)OH group, which is involved in inter-molecular H-bonding
(c)A terminal alkyne group
(d)OH group, present in severely sterically hindered environment
