Homework Answers
Answer:
The broad peak at 3274 cm-1 is for an alcohol (-OH) group.
The weak peak at 2145 cm-1 indicates the presence of a C-C triple bond. It must be an internal alkyne because there is no narrow peak at around 3300 cm-1, which is shown by alkyne C-H stretch.
The peaks at 2929 and 2884 cm-1 are for aliphatic saturated C-H stretch. So, there is no olefinic or aromatic proton.
The peaks at 1414 and 1333 cm-1 are for O-H in plane bending vibrations coupled with C-H wagging vibration.
