Question 1. When hair is dry, protein molecules in the hair structure form hydrogen bonds with

other protein molecules in the same hair structure
water molecules, H2O
other protein molecules from another hair structure
water molecules, H2O which also forms hydrogen bonds with protein molecules from another hair structure

Discuss Question

Answer: Option A. -> other protein molecules in the same hair structure

Question 2. Why can compounds that can form hydrogen bonds have higher boiling points than compounds that cannot form hydrogen bonds?

Compounds that can form hydrogen bonds need to overcome weak Van der Waals attraction forces
