Consider the following organic molecules, which have approximately the same molar masses but might contain different functional groups:CH₃CH₂CH₂CH₂CH₂CH₃, CH₃CH₂CH₂CH₂CHCH₂, CH₃CH₂CH₂CH₂CH₂OH, CH₃CH₂CH₂CH2CHO, CH₃CH₂CH₂COOH, CH₃CH₂COOCH₃, CH₃CH₂COCH₂CH₃, CH₃CH₂CH₂CH₂OCH₃.

(a) Draw a Lewis structure for each molecule, name it, and classify it by any functional group that is present.

(b) Which molecules are isomers of each other? Are any chiral? If so, which ones? 

(c) For each molecule, list the types of intermolecular forces that are present. 

(d) Use your answers to parts (a) and (b) to predict the order of boiling points, from lowest to highest.
