1. "Aromatic compounds must be a planar cycle of sp2 hybridized atoms, the p-orbitals of which are oriented parallel to each other. These overlapping p=orbitals generate an array of pie-molecular orbitals." Can you explain this sentence in great details ?

2. State 1 structure when the carboxyl group exists as an anion in sodium salt.

✔ 最佳答案
1)頭一句是說:在aromatic cpd中的每一個碳份子都是sp2雜化(hybridized)而成的.因為在aromatic cpd中的碳份子是由三個σ-bond及一個π-bond組成,而由於每一個碳份子都是sp2雜化,也即是說,每一個碳份子都會有一個未雜化(unhybridized) 的spz軌道,而這些spz軌道是可以互相重疊的,從而在aromatic ring的上及下成為一個由spz軌道互相重疊的大 π-bond.
2)I am not sure and just I think CH3COO-Na+ may be one of the cpds since COO group has the carboxyl(>C=O) group.
cpd = compound
I hope you will find them helpful.
