Answer to Question #73054 in General Chemistry for jessica

Question

Rank the compounds, except octane, from least polar to most polar.
a. ethane C2H6
b. ethanol C2H6O (CH3CH2OH)
c. ethanoic acid C2H4O2 (CH3COOH)
d. methoxymethane C2H6O (CH3OCH3)
e. octane C8H18
f. 1-octanol C8H18O (CH3CH2CH2CH2CH2CH2CH2CH2OH)

Answer 1

Polarity is a property that characterizes the separation of charges in molecules, their fragments or individual bonds and determines their dipole moment. By increasing the polarity, that is from least polar to most polar, the compounds are arranged in a row:
a. ethane C2H6
d. methoxymethane C2H6O (CH3OCH3)
b. ethanol C2H6O (CH3CH2OH)
f. 1-octanol C8H18O (CH3CH2CH2CH2CH2CH2CH2CH2OH)
c. ethanoic acid C2H4O2 (CH3COOH)
