Question

Which of the following arises from interaction of dipoles? 3. a) lonic bond b) Covalent bond c) Metallic bond d) Hydrogen bond

Answer 1

d) Hydrogen bond

Step-by-step explanation:

Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.

Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.

Answer 2

Hydrogen bond

Step-by-step explanation:

Hydrogen bond is a type of dipole dipole interaction.

Hydrogen bond is present between the hydrogen atom attached to an electronegative atom and other electronegative atom. Compounds in which hydrogen is attached with N, F and O, show hydrogen bonding.

As N, F and O are more electronegative than H, so a positively charge is develop on H atom and negative charge is develop on electronegative atom.

Hydrogen bond is a weaker bond. It is weak as compared to ionic bond and covalent bond but stronger than van der Waals interaction.

Ionic bond is formed by the complete transfer and gain of electrons. It is a electrostatic attraction between positively charged and negatively charged species. Fox example bonding in NaCl

Covalent bond is formed by the sharing of electrons between two atoms. For example bonding in Cl_2.

Metallic bond is present between mobile electrons and positively charged kernels. It exist in metals only.
