1.	Write the resonance structures of = CH– CHO and arrange them in order of decreasing stability.
Answer» lowing structures are CONSIDERED relatively stable: Structures having filled octet a for second ROW elements (C, N, O, F) are stable. Structures having minimum number of formal charges and maximum number of BONDS. STRUCTURE in which negative charge appears on the most electronegative atom (C < N < O)
