Cyclohexane shares its general formula with the alkane homologous series.

Here's why:

* Cyclohexane Formula: C₆H₁₂

* General Alkane Formula: C_nH_2n+2

If we plug in n=6 (for 6 carbon atoms) into the alkane formula, we get:

* C₆H₂₍₆₎₊₂ = C₆H₁₄

However, cyclohexane has two fewer hydrogen atoms than a straight-chain alkane with 6 carbons (hexane). This is because the cyclic structure forms a ring, eliminating the need for two hydrogen atoms that would be present in a straight chain.

Therefore, cyclohexane shares the same general formula as alkanes, but its structure is different, making it a cycloalkane.
