Question

Which of the following statements most accurately describes the physical properties of long
alkyl chains?
a. Long alkyl chains are non-polar and hydrophobic. They readily dissolve in water and
hexane. When close-packed the chains are held together by permanent dipole interactions.
b. Long alkyl chains are polar and hydrophilic. They readily dissolve in water but not
hexane. When close-packed the chains are held together by permanent dipole interactions.
c. Long alkyl chains are non-polar and hydrophobic. They readily dissolve in hexane but
not in water. When close-packed the chains are held together by ionic interactions.
d. Long alkyl chains are non-polar and hydrophobic. They readily dissolve in hexane but
not in water. When close-packed the chains are held together by transient dipole
interactions.
e. Long alkyl chains are polar and hydrophobic. They readily dissolve in hexane but not
water. When close-packed the chains are held together by transient dipole interactions.
