The vibration of which bond gives an ir absorption that distinguishes between the following two compounds? ch3 ch2 ch2 oh ch3 ch2 och3 what is the approximate wavenumber (cm-1) of that band? select answer 1050 1250 1450 1700 3500

3500cm-1

Explanation: The -OH bond absorbs IR and vibrates at a characteristic and many times distinctive wave number of 3500cm-1. The -C=O would vibrate at 1700cm-1 though not clearly because -C-O bond typically vibrates around this point

the correct answer would be d. hope this !
