Abstract The analysis of the structure is the key to recognizing the properties of the organic compounds. Taking the carbonyl group:polar multiple bonds as the object of knowledge, based on the understanding of the chemistry principle, this paper presents the deep teaching about properties of ketone carbonyl groups, aldehyde groups and polyhydroxy aldehydes from perspectives of the hybridization form of central atom, the electronegativity of bonding and the polarity of the covalent bond in the unit teaching of aldehydes, ketones and glucose. The teaching process can help students achieve the progression of cognition from simple function group to multiple functional group and the interactions between multiple functional groups, and promotes the development of the students’ academic literacy and core competencies.
