The sole of a gecko's foot is covered with millions and millions of small,dry "hairs" that make direct contact with surfaces,and allow geckos to walk up walls and dangle from the ceiling.Experiments showed that the "hairs" stick well to strongly hydrophobic,strongly hydrophilic,and electrically neutral surfaces and that covalent bonds were not involved.What noncovalent bond is probably involved in the foot adhering to a surface?

Question

Quizplus · Accepted Answer

The noncovalent bond that is most likely involved in gecko's foot adhering to a surface is hydrogen bonds. This is because hydrogen bonds are relatively weak but can be very numerous, allowing the foot to create a strong overall adhesion with the surface. Ionic bonds would be too strong and rigid for this purpose.
