Question

How are hydrogen bonds different from covalent bonds? (A- They have valance electrons) (B-The resulting compounds contain carbon) (C-Hydrogen bonds are weaker bonds that form molecules that ga e a slight positive charge on one side and a slight negative charge on the other)

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

A hydrogen bond is defined as a weak bond that is formed between an electropositive atom (generally hydrogen atom) and an electronegative atom like oxygen or nitrogen.

Due to difference in the electronegativity of atoms in a compound containing hydrogen bond there occurs a partial positive charge on hydrogen atom and a partial negative charge on the electronegative atom.

For example, $H_{2}O$ is a polar molecule and contains hydrogen bonds.

Whereas a covalent bond is defined as the bond formed due to sharing of electrons between the two chemically combining atoms.

Thus, we can conclude that hydrogen bonds are different from covalent bonds because hydrogen bonds are weaker bonds that form molecules that ga e a slight positive charge on one side and a slight negative charge on the other.

Answer 2

C Hydrongen bonds are weaker bonds that form molecules that get a slight positive charge on one side and a slight negative charge on the other.
