Place the substances in order of increasing viscosity. CH₃CH₂CH₂CH₃ H₂NCH₂CH₂NH₂ CH₃CH₂CH₂NH₂

Question

Quizplus · Accepted Answer

Viscosity is the measure of a fluid's resistance to flow. The greater the viscosity, the more resistant the fluid is to flow. Based on the given substances, we can see that as the number of sulfur atoms in the molecule increases, the viscosity also increases. Therefore, CH₃ (having three sulfur atoms) will have the highest viscosity and H₂ (having no sulfur atoms) will have the least. Based on this, we can order the substances in increasing order of viscosity as: H₂ < CH₂NH₂ < CH₃CH₂CH₂CH₃. Therefore, the best choice is A.
