Question 4 1 pts Which of the following statements is true? Carbonyl compounds are Lewis acids because the oxygen has a partial negative charge and can donate electrons. Carbonyl compounds are Lewis acids because the double bond has electron density and can donate electrons. Carbonyl compounds are Lewis acids because the carbon has a partial positive charge and can accept electrons Carbonyl compounds are Lewis bases only.
