The formula for cyclobutene is (C4H6): {-CH2-CH=CH-CH2-} It calls for making a ring with the ends -C and C- to be connected, and formed in the shape of a square. In addition to the ring there is a bond of double C=C.
Make the 'ring' ( cyclo ) complete by virtually connecting both ends (at {-C and C-} ) and complete it by forming a square. Besides the ring there is also a double C=C bond.
This is the formula of cyclobutene (C4H6): {-CH2-CH=CH-CH2-}
I believe that it's

2,2,3- trimethyl pentane has the structural shape. CH3-C(CH3)2-CH(CH3)-CH2-CH3 C8H18 is the condensed /reduced formula.
Cyclohexane which is a cycloalkanes, has a structural formula of C6H12. It may be written in a condensed form as (CH2)6.
The complete or full structural formula shows all the atoms and their bonds separately. The condensed structural formula shows the atoms present but does not show the bonds.
------ The condensed structural formula is simply a shortened version of the complete structural formula. -------The complete formula indicates all of the carbon and hydrogen atoms. The condenced formula groups the hydrogen atoms with each of the carbon atoms.
The structural formula show the position of atoms in a molecule.
