Structure of Molecule
The following topics are covered in this video lecture:
Structure of Molecule
Covalent Bond
Types of Covalent Bond
What type of elements have tendency of sharing of electrons?
If repulsive forces dominate to attractive forces will a covalent bond form?
Considering the electronic configuration of nitrogen atom, how many electrons are involved in bond formation and what type of covalent bond is formed.
Point out the type of covalent bonds in the following molecules
CH4, C2H4, H2, N2, and O2.
What is a lone pair? How many lone pairs of electrons are present on nitrogen in ammonia?
What is difference between bonded and lone pair of electron and how many bonded pair of electrons are present in NH3 molecule?
What do you mean by sigma sign and why it develops?
Why does oxygen molecule not form a polar covalent bond?
Why has water polar covalent bonds?
