Question

Non directional bond is present in:

• A. $KF$
• B. $H_2$
• C. $H_{2}O$
• D. Both $A$ and $B$

Answer 1

Answer: (D)

Both $A$ and $B$

In general, ionic bond is a non directional bond and covalent bond is a directional bond.

The meaning of covalent bonds being directional is that atoms bonded covalently prefer specific orientations in space relative to one another.

$\Rightarrow KF$ has a non directional bond (Ionic bond)

$\Rightarrow$Even though, $H_2$ has a covalent bond, it is still non directional as the molecule is linear and there is no difference of electronegativity. There is no specific orientation of H with respect to other H.

$\Rightarrow H_{2}O$ has a directional bond.

$\therefore$ Both $KF$ & $H_2$ have non directional bond present in them.
