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.

Circle the compound in the following pairs corresponding to the physical properties. Write the intermolecular force directly under each compound (ID,DD,HB). a) Highest BP: CH3OH  or   CH3SH b)  Highest heat of Vap: H20  or   Cl2 c) Highest surface tension: CH3CH2CH2CH3 or CH3CH2CH2CH2CH2CH3 d) Highest BP: Si(CH3)4  or NF3 e) Highest vapor pressure: CH3NHCH3 or BCl3

3) Draw and name an alcohol that has 3 different substituents, one should be an alkene. You cannot have the same example as someone else.

art C: Applications /17 1.Draw the chemical reaction that links an alcohol to each organic compound. Identify the type of chemical reaction. (4 marks) a) aldehyde b) ketone c) carboxylic acid d) ester
