Q7

What are the main reason(s) that the alkenes have lower boiling points than the alcohol? (Check all that apply) The alkenes are more symmetric than the alcohol. The alkenes have lower molecular masses O The alkenes are low in polarity and mainly experience London dispersion forces between them. The alcohol has a much higher molecular weight than the alkenes. The dominant intermolecular force in the alcohol are hydrogen bonds.
