The C-O absorption in carboxylic acids appears around 1250 cm 1. The C-O absorption in an alcohol appears around 1050 cm1. Explain why. 1250cm-1 .1 1050cm O Only compound I has resonance, causing it to have a higher stretching absorption. O Only compound II has resonance, causing it to have a higher stretching absorption. O Compound Il has more possible resonance structures, increasing the single bond character of the carbonyl group. O Compound I has more possible resonance structures, increasing the single bond character of the carbonyl group. O Compound I has a C to O bond with more single bond character than that of compound II, increasing the expected stretching absorption of the bond.

I would want an explanation why this is the answer maybe s simple drawing with the curve arrows.

The C-O absorption in carboxylic acids appears around 1250 cm1. The C-O absorption in an alcohol appears around 1050 cm1. Explain why. 1250cm-1 -1 1050cm O Only compound I has resonance, causing it to have a higher stretching absorption. O Only compound II has resonance, causing it to have a higher stretching absorption. O Compound Il has more possible resonance structures, increasing the single bond character of the carbonyl group. O Compound I has more possible resonance structures, increasing the single bond character of the carbonyl group. O Compound I has a C to O bond with more single bond character than that of compound II, increasing the expected stretching absorption of the bond.
