Question

What kind of bond is formed by hydrogen and oxygen?

Answer 1

`"A polar covalent bond............"`

Explanation:

Hydrogen is covalently bound to oxygen in a `"2-centre-2-electron"` bond. The oxygen and the hydrogen participate in a covalent bond, and such bonds are observed in water, alcohols, and also hydrogen peroxide, i.e. `OH_2,ROH, H-O-O-H`,

Because in the `-O-H` bond there is some unlittle degree of polarity, i.e. charge separation, `stackrel(delta+)H-stackrel(delta-)O-stackrel(delta+)H`, to give molecular dipoles, such polarity gives rise to the phenomenon of intermolecular hydrogen bonding.
