Which of the following are valid reasons why vegetable oil has a greater viscosity than diethyl ether,CH₃OCH₃?
1) Oil molecules have long chains that become entangled.
2) Unlike diethyl ether,oil molecules are not held together by hydrogen bonds.
3) Intermolecular forces are greater for the larger oil molecules.

1) Long chains of oil molecules can become entangled, leading to a higher viscosity.
2) Diethyl ether molecules are held together by dipole-dipole interactions and London dispersion forces, while oil molecules have stronger intermolecular forces due to their larger size and surface area.
Therefore, statements 1 and 3 are valid reasons for why vegetable oil has a greater viscosity than diethyl ether. Statement 2 is not a valid reason for this difference in viscosity.
