Interpretation: The Lewis structure for N, N-dimethylformamide molecule needs to be drawn. The resonance structures needs to be drawn to show the double bond character in C-N bonds.
Concept Introduction: In a Lewis structure, the atoms are arranged in such a way that all the atoms have complete octets. The total number of valence electrons is first calculated in all the atoms present in the molecule whose Lewis structure needs to be drawn. The skeleton is made in such a way that most electronegative atom is always placed at terminal position. The total number of electrons is distributed in all the atoms such that all the atoms have complete octet.
Resonance is a process that involves the delocalization of electrons to form different Lewis structure of a compound or ion. Not all compounds can show resonance.
