Chemical Bonding MCQs : This section focuses on the "Chemical Bonding" in Chemistry Class 11. These Multiple Choice Questions (MCQs) should be practiced to improve the Chemistry Class 11 skills required for various exams, interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
____________ refers to the formation of a chemical bond between two or more atoms, molecules, or ions to give rise to a chemical compound.
A. Molecular Structure
B. Chemical Bonding
D. None of the above
Explanation: Chemical Bonding refers to the formation of a chemical bond between two or more atoms, molecules, or ions to give rise to a chemical compound. These chemical bonds are what keep the atoms together in the resulting compound.
How many primary types of chemical bonds?
Explanation: There are 4 primary types of chemical bonds which are formed by atoms or molecules to yield compounds. These types of chemical bonds include: Ionic Bonds, Covalent Bonds, Hydrogen Bonds and Polar Bonds
_________ is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
A. Covalent Bonds
B. Hydrogen Bonds
C. Ionic bonding
D. Polar Bonds
Explanation: Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
Atom develops a positive charge and is called the cation
C. Can be true or false
D. Can not say
Explanation: True, atom develops a positive charge and is called the cation
The equilibrium distance between the centres of the nuclei of the two bonded atoms is called its __________.
A. Size of the atoms
B. The multiplicity of Bond
D. Bond length
Explanation: At equilibrium distance, the atoms keep on vibrating about their mean position. The equilibrium distance between the centres of the nuclei of the two bonded atoms is called its Bond length.
Molecules are held together in a crystal by
A. hydrogen bond
B. electrostatic attraction
C. Van der Waal’s attraction
D. dipole-dipole attraction
Explanation: Molecules are held together in a crystal by Van der Waal’s attraction
Find the molecule with the maximum dipole moment
Explanation: NH3 molecule with the maximum dipole moment
Which among the following chemical bond were described by Kossel and Lewis?
A. Metallic bond
B. Polar covalent bond
C. Coordinate bond
D. Ionic and Covalent bond
Explanation: Both Ionic and Covalent bond arise from the tendency of atoms to attain stable configuration of electrons.
Which among the following is not a property of Ionic bond?
A. Losing of electrons
B. Gain of electrons
C. Sharing of electrons
D. Transfer of electrons
Explanation: Ionic bond results from Losing, Transfer and Gain of electrons. But the transfer of electrons is a property of Covalent bond.
A covalent bond indicates the sharing of electrons between atoms.
C. Can be yes or no
D. Can not say
Explanation: A covalent bond indicates the sharing of electrons between atoms. Compounds that contain carbon (also called organic compounds) commonly exhibit this type of chemical bonding. The pair of electrons which are shared by the two atoms now extend around the nuclei of atoms, leading to the creation of a molecule.
