Q:

Which combination of atoms can form a polar covalent bond?

A) H and Br B) H and H
C) Na and Br D) N and N
 
Answer & Explanation Answer: A) H and Br

Explanation:

Only H and Br form Polar Covalent Bond.

 

Covalent bonding:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

1. Polar Covalent Bond

2. Nonpolar Covalent Bond

 

1. Polar Covalent Bond:

A Polar Covalent Bond is created when the shared electrons between atoms are not equally shared. This occurs when one atom has a higher electronegativity than the atom it is sharing with. The atom with the higher electronegativity will have a stronger pull for electrons (Similiar to a Tug-O-War game, whoever is stronger usually wins). As a result, the shared electrons will be closer to the atom with the higher electronegativity, making it unequally shared.

 

2. Nonpolar Covalent Bond:

A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; also known as diatomic elements. Nonpolar covalent bonds have a similar concept as polar covalent bonds; the atom with the higher electronegativity will draw away the electron from the weaker one.

 

Here H and H and N and N form Non-polar covalent bonds. Na and Br form the ionic bond.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

There's more than the 101-seater dining table at the Falaknuma Palace that is awe inspiring. The library done in rosewood and mahogany is a place that will force anyone to pause, if only to admire the fine original polish, the furniture and the walnut carved high roof. The last is supposedly an imitation of the one at Windsor Castle.

The library is almost the size of a large banquet hall and acts as the passage to other parts of the palace including the dining area. For years the palace had no librarian because they couldn't find the right person to do justice to the treasure trove of books collected by the Nizam's family over several decades. That is until they found Asif Husain Arastu who belongs to the family that owned the famous A A Husain book store in Abids. So when his friend and historian Anuradha Naik pointed out the palace's requirement at the library, Husain was delighted. On his very first day as the librarian at the magnificent Taj Falaknuma palace, Asif Husain found a reference book on 'How to paint grass' by Alfred East.

The roof of the library had carvings made of which wood?

A) Rosewood B) Mahogany
C) Sandalwood D) Walnut
 
Answer & Explanation Answer: D) Walnut
