Avg score: 68% • Most missed: “No atoms are shown while representing structures in bond-line formula.”

Structural formulae can be further condensed by enclosing the repetitive structural unit within a bracket and placing an integer as a subscript indicating the number times the structural unit gets repeated.

Example:

CH3CH2CH2CH2CH2CH2CH3 can be condensed to CH3(CH2)5CH3

CH3CH2CH2CH2CH2CH2CH2COOH can be condensed to CH3(CH2)6COOH
