Question

why hydrogen bonding is directional bond and what is directional bond​

Answer 1

Answer:

hydrogen bond is a kind of directional interaction between the donor group (X–H, X = N, O, halogen, etc.) and the acceptor group (A, A = O, N, S, etc.). In a donor group, the difference in electronegativity between X and H atoms makes the X–H bond inherently polar, with a partial atomic charge on the H atom. direction of bond means =The meaning of covalent bonds being directional is that atoms bonded covalently prefer specific orientations in space relative to one another. As a result, molecules in which atoms are bonded covalently have definite shapes.
