Give the name,formula and structure of the cycloalkane which has only one structure.

(N/A) The simplest cycloalkane is cyclopropane $(C_3H_6)$.
It consists of a three-membered carbon ring where each carbon is bonded to two hydrogen atoms.
Since all positions in the ring are equivalent,it has only one possible structure.
Name: Cyclopropane
Formula: $C_3H_6$
Structure: $A$ triangle with a $CH_2$ group at each vertex.
