Question

What is the type of bond in which electrons are shared unequally?

Answer 1

`"A polar covalent bond..."`

Explanation:

Covalent bonds result from the sharing of electrons between atoms. For homonuclear diatomics, i.e. `H_2`, `He_2^+`, `C_2`, `N_2`, `O_2`, the atoms participating in the molecule have EQUAL electronegativity and do not polarize electorn density towards themselves...

On the other hand, heteronuclear diatomic molecules provide rich examples of polar covalent bonds, for instance, the hydrogen halides...`stackrel(+delta)H-stackrel(delta-)X`...in aqueous solution charge separation tends to be great as to break the `H-X` bond and gives quantities of `H_3O^+` and `X^-`...
