Question

Which kinds of bonding can be found in a sample of H2O?

a) hydrogen bond only b) ionic bond c) polar covalent bond d) non polar bond

​

Answer 1

Answer:

In H2O molecule, two water molecules are bonded by a Hydrogen bond but the bond between two H - O bonds within a water molecule are covalent.

Answer 2

Solution:

Option a & c is correct.

Explanation:

• In H2O a hydrogen (H) atom is bound to a highly electronegative atom oxygen (O) Such H atom experiences electrostatic force of attraction to some other nearby highly electronegative atom (such as O atom of second water molecule) to form a bond called hydrogen bond.

• Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge
