Question

Why is the conjugate acid of morpholine more acidic than the conjugate acid of piperidine? Why is the conjugate acid of morpholine more acidic than the conjugate acid of piperidine? The oxygen in morpholine withdraws electrons inductively, which makes protonated morpholine the stronger acid. The oxygen in morpholine does not withdraw electrons inductively, which makes protonated morpholine the stronger acid. The sp2 oxygen in morpholine is less electronegative than the sp2 carbon of piperidine, which makes protonated morpholine the stronger acid. The sp2 oxygen in morpholine is more electronegative than the sp2 carbon of piperidine, which makes protonated morpholine the stronger acid.

Answer 1

The oxygen in morpholine withdraws electrons inductively, which makes protonated morpholine the stronger acid.

Step-by-step explanation:

In Chemistry, acidity has to do with ease with which hydrogen ion is lost from a substance. Hence in a substance that has greater acidity, hydrogen ion is easily lost as a proton. This easy loss of hydrogen ion is usually caused by a particular reason which is related to the structure of the substance.

In comparing the acidity of protonated morpholine and piperidine, we find out that morpholine has an oxygen atom which withdraws electrons inductively thereby making the N-H bond in protonated morpholine weaker and enhances the loss of a hydrogen ion in protonated morpholine as a proton.
