#16
Front (Question)

Aromaticity implies 1

Back (Answer)

A cyclic structure with conjugated pi bonds containing unhybridized p orbitals that can overlap with other ring carbons to form a delocalized pi e- system

#17
Front (Question)

Aromaticity implies 2nd

Back (Answer)

A structure in which delocalization of the pi-e- system lowers the total electronic energy

#18
Front (Question)

Hückel’s rule

Back (Answer)

A compound is aromatic if the number of its pi electrons is equal to 2+4n, where n is zero or an internet snd represents filled electron shells; for n=0,1,2, aromatic systems have 2,6,10 pi electrons

Antiaromatic

Back (Answer)

When pi electron delocalization increase the electronic energy
