Question

If a salamander relied on hydrogen bonds to cling to surfaces, what type of surface would cause the most problems for this animal? A a surface coated with a thin film of water b a surface made with carbon and hydrogen atoms covalently bonded together c a surface made with carbon, hydrogen, and oxygen atoms covalently bonded together d a surface made with carbon, hydrogen, nitrogen, and oxygen atoms covalently bonded together e a surface made with silicon and oxygen atoms covalently bonded together

Answer 1

Option-B (A surface made with carbon and hydrogen atoms covalently bonded together)

Step-by-step explanation:

Hydrogen Bond interactions are formed between a partial positive hydrogen atom directly bonded to most electronegative atom (Fluorine, Oxygen or Nitrogen) of one molecule and a most electronegative element (partial negative) present on neighbor molecule.

It means that hydrogen bonding exist between two regions when hydrogen is directly bonded to any most electronegative element present on either of the region.

While, in option-B one region (the surface) is lacking such type of hydrogen atom as at this surface hydrogen is attached to less electronegative atom (i.e Carbon). Therefore, no hydrogen bond interactions take place between Salamander feet and the surface.
