bonds

Question 1

Covalent bonds are formed by…

Answer 1

the overlapping of atomic orbitals

Question 2

The Sigma (σ) Bond

Answer 2

head-on positive (same phase) overlap of atomic orbitals along the internuclear axis.

Question 3

____ are the strongest covalent bonds

Answer 3

Sigma bonds

Question 4

s-s Overlapping (Sigma bonds)

Answer 4

• one ‘s’ orbital from each participating atom undergoes head-on overlapping along the internuclear axis.
• An s orbital must be half-filled before it overlaps with another.

Question 5

s-p Overlapping (sigma bond)

Answer 5

one half filed s orbital overlaps with one half-filled p orbitals along the internuclear axis, forming a covalent bond.

Question 6

p-p overlapping (sigma bond)

Answer 6

one half-filled p orbital from each participating atom undergoes head-on overlapping along the internuclear axis

Question 7

The Pi (π) Bond

Answer 7

formed by the sidewise positive (same phase) overlap of atomic orbitals along a direction perpendicular to the internuclear axis.

Question 8

How Many Pi/sigma Bonds Exist in Double Bonds?

Answer 8

one pi bonds and one sigma bond

Question 9

What is the Number of Sigma and Pi bonds in a Benzene Molecule?

Answer 9

12 sigma bonds and 3 pi bonds

Question 10

How Many Pi/sigma Bonds Exist in Triple Bonds?

Answer 10

one sigma bond and two pi bonds
