- ох 4-tert-butyl oxy cyclohex-1-ene Incorrect, 1 attempt remaining The systematic name of this compound classifies the -OR group as a substituent of the hydrocarbon, which is considered the principal functional group. The ether substituent is named with the suffix 'oxy'. The general format for the systematic name of a hydrocarbon is: [prefix/substituent] + [parent] + [functional group suffix] Substituents are listed in alphabetical order. Molecules with a chiral center will indicate the absolute configuration at the beginning of its name with the R and S notation.arrow_forward5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature.
