Monohar Pandey Solutions for Exercise 4: Exercise 4

Consider the following statements.

1. Formation of cations occurs by loss of electrons.

2. Formation of anions occurs by gain of electrons.

Which of the statement given above are correct?

Molten NaCI is a good conductor of electricity is due to

Assertion (A) Double bond cause more repulsion than single bonds.

Reason (R) Triple bonds cause more repulsion than a double bond.

Consider the following statements.

1. Metallic bond are malleable and ductile.

2. Covalent compounds are generally non-conductor of electricity.

3. Ionic compounds are good conductor of electricity in molten or liquid state.

Which of the statements given above are correct?

Assertion (A) An ionic bond is formed when a metal atom transfer one or more electrons to a non-metal atom.

Reason (R) The metal atom becomes cation and the non-metal the anion.

Consider the following Statements.

1 . Strength of certain acid and bases can be explained on the basis of hydrogen bonding.

2. Alcohol and amines are soluble in water due to H-bonding.

Which of the Statement given above is/are correct?

Consider the following Statements:

1. The dipole moment helps to predict whether a molecule in polar or non-polar.

2. The melting point and boiling point of coordinate compounds are higher than covalent compound but lesser than the ionic compounds.

Which of the statement given above is/are correct?

Assertion (A) The covalent bond is formed by the sharing of pairs of electrons between atoms.

Reason (R) Covalency is greatest between atoms of different electronegativities.
