Explain fundamental frequency than that of propionaldehyde

Reference no: EM13547437

1. Based on resonance structures for acrolein, do you expect the C=O stretch in acrolein to be of higher fundamental frequency or lower fundamental frequency than that of propionaldehyde?

2.Which do you think would have a higher carbonyl stretch frequency - hexachloroacetone or acetone - explain.

3.Different hybridizations give rise to different vibrational frequencies. Terminal alkynes have C-H stretching frequencies of about 3300 cm-1; alkene C-H stretching frequencies are around 3100 cm-1, and alkane C-H stretching frequencies are around 2900 cm-1. Explain these observations - how does ‘s'-character affect vibrational frequencies?
