Which of the following elements cannot participate in hydrogen bond formation?

Options

A. `C`
B. `O`
C. `N`
D. `F`

Answer

A

Explanation

Strong hydrogen among occurs among polar covalent molecules containing `H` and one of the three small, highly electronegative elements `F,O,or N`. Recently , careful studies in solids and of the arrangements of molecules in solids have led to the conclusions that the same kind of attraction occurs (although more weakly) when `H` is bonded to `C` . In some cases, very weak `C-H....O` ''hydrogen bonds'' exist. Similar observations suggest the existence of weak hydrogen bonds in `Cl` atoms, such a s`O-H.....Cl`. However, most chemist usually restrict the usage of the term ''hydrogen bonding'' to compounds in which `H` is covalently bonded to `F,O,or N`. Therefore, it is treated as a separate category.
