Bonding, Functional Groups

Question 1

What is a covalent bond

Answer 1

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. Examples are H2, O2, H2O, and CO2

Question 2

The structural formula of a compound is its Lewis structure, which
shows how various atoms are connected to each other

Answer 2

True

Question 3

Properties of covalent bonds

Answer 3

1) Covalent compounds are made up of neutral molecules.
2) The melting and the boiling points of covalent compounds are generally low.
3) Covalent compounds are insoluble in water but soluble in organic solvents.
4) Covalent compounds do not conduct electricity.

Question 4

What is Bond length

Answer 4

Bond length can be defined as the average distance between

the nuclei of the atoms which are covalently bound together

Question 5

What is bond angle

Answer 5

Bond angle

can be defined as the angle between the atoms in a bond

Question 5

What is bond angle

Answer 5

Bond angle
can be defined as the angle between the atoms, forming the bonds to the
same atom

Question 6

What is bond energy

Answer 6

Bond energy is an average value for a particular bond

Question 7

What is hybridization

Answer 7

Hybridization is a theoretical concept which enables as

realistic modelling of molecular structure as possible

Question 8

Types of hybridization

Answer 8

sp hybridization (beryllium chloride, acetylene)
sp2 hybridization (boron trichloride, ethylene)
sp3 hybridization (methane, ethane)
sp3d hybridization (phosphorus pentachloride)
sp3d2 hybridization (sulphur hexafluoride)
sp3d3 hybridization (iodine heptafluoride)

Question 9

What is a functional group

Answer 9

A functional group can be defined as an atom or a
group of atoms in a molecule which exhibits characteristic chemical
properties
