Q.1
How can hydrogen bonds form between cellulose in paper and water molecule, Hon the finger?
  • By pouring a bucket of water on the paper
  • Water molecules, H2O on the wet finger will form hydrogen bonds with cellulose in paper
Q.2
When hair is wet, 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
Q.3
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
Q.4
What is the basis of hydrogen bond?
  • Attraction forces between hydrogen atom bonded with another hydrogen atom
  • Attraction forces between hydrogen atom bonded with a high electronegativity atom (F, O, N)
  • Attraction forces between hydrogen atom bonded with a high electronegativity atom (F, O, N) with atom (F, O, N) of another molecule
  • Attraction forces between hydrogen atom with another hydrogen atom of another molecule
