A compound with molecular formula C6H10O, shows absorptions at 1720 cm-1 and at 2980 cm-1 on the IR spectrum. Draw a possible structure for this compound.

Homework Answers

Answer #1

In the IR spectrum each peak shows the characteristic presence of particular organic functional groups in the compound.

Here in the question C6H10O shows absorption at 1720 cm-1 and at 2980 cm-1.

1720 cm-1 belongs to the C=O stretch of aldehydes, Ketones or carboxylic acid (1630 cm-1 to 1740 cm-1)

&

2980 cm-1 belongs to the alkane (3000–2850 (m) C–H stretch alkanes)

Since Molecular formula shows presence of oxygen , its structure can be drawn from above information as follows,
