Explain: $Anthracene$ and $Phenanthrene$ are aromatic in nature.

(N/A) compound is considered aromatic if it follows $Huckel's$ rule,which states that the molecule must be planar,cyclic,and contain $(4n + 2) \pi$ electrons,where $n$ is an integer $(n = 0, 1, 2, ...)$.
$1$. $Anthracene$ $(C_{14}H_{10})$: It consists of three fused benzene rings in a linear arrangement. It has $14$ $\pi$ electrons. According to $Huckel's$ rule,$4n + 2 = 14$,which gives $4n = 12$,so $n = 3$. Since $n$ is an integer,$Anthracene$ is aromatic.
$2$. $Phenanthrene$ $(C_{14}H_{10})$: It consists of three fused benzene rings in an angular arrangement. It also has $14$ $\pi$ electrons. Similarly,$4n + 2 = 14$ results in $n = 3$. Since $n$ is an integer,$Phenanthrene$ is also aromatic.
