The given molecule is aromatic

Vedclass · Answer

(A) The given molecule is $1,2-dihydronaphthalene$. $1$. It is not aromatic because it does not satisfy $H$ückel's rule ($4n+2$ $\pi$ electrons in a planar cyclic conjugated system). $2$. It has $4$ $\pi$ electrons in the conjugated system (two double bonds),not $6$. $3$. The molecule is not planar because the saturated carbon atoms ($sp^3$ hybridized) disrupt the planarity of the ring system. $4$. Since the molecule is not fully conjugated,it does not have eight parallel pure $p-$ orbitals. Comparing the options,statement $D$ is correct (the molecule is not planar),but statement $A$ is definitely wrong as it is not aromatic. Statement $B$ is also wrong as it has $4$ $\pi$ electrons. However,in the context of typical multiple-choice questions for this specific structure,the most fundamentally incorrect statement regarding its aromaticity is $A$.

Which of the following statements is wrong for the given molecule?
