Question
Shown below is an arrow pushing diagram describing a reaction between water and a peptide bond. Which of the following statements are correct regarding this reaction? [Select all that apply.] O-H An oxygen atom acts as a nucleophile. A bond forms between the hydrogen in water and the carbonyl carbon. A carbon atom acts as an electrophile. The double bond in the carbonyl carbon breaks, completely separating the carbon and oxygen atoms. A carbon atom acts as a nucleophile. A bond forms between the oxygen in water and the carbonyl carbon. The double bond in the carbonyl carbon breaks, leaving only a single bond. An oxygen atom acts as an electrophile.Explanation / Answer
An oxygen atoms acts as a nucleophile - Correct, oxygen in water acts as an electrophile by donating the electron
A bonds form between hydrogen in water and carbonyl carbon - False, the bond will be formed between carbon and oxygen and not carbon and water
Carbon acts an electrophile - TRUE, since carbon will have a + charge and it will accept electrons
Double bond breaks completely - FALSE, single bond will still be present
A carbon acts as nucleophile - FALSE
A bond forms between oxygen in water and carbonyl carbn - TRUE
Double bond will become single bond - TRUE
Oxygen acts as an electrophile - TRUE
