The hydrocarbon having an analogous structure to that of $\mathrm{P}_{4} \mathrm{O}_{6}$ is
(a) $\left[(\mathrm{CH})_{4}\left(\mu-\mathrm{CH}_{2}\right)_{6}\right]$
(c) $\left[\left(\mathrm{CH}_{2}\right)_{4}(\mu-\mathrm{CH})_{6}\right]$
(b) $\left[(\mathrm{CH})_{6}\left(\mu-\mathrm{CH}_{2}\right)_{4}\right]$

Answer Answer: A ✓ checked by 4AB · confidence high
Explanation P₄O₆ is a P₄ tetrahedron with six O atoms bridging its edges. The hydrocarbon analogue puts CH at the four corners and CH₂ across the six edges: [(CH)₄(μ-CH₂)₆] (adamantane-like).
