Organic chemistry

Question 1

What influences the properties of organic compounds?

Answer 1

Organic compounds structures are determined by the molar masses and number of polarities of functional groups of the compound. The electrons of the electrons of polar and non-polar cloud.

Question 2

What makes the properties of fixed organic groups?

Answer 2

Polar organic compounds contain one or more functional groups. Polar compounds contain fixed regions of functional groups.

Question 3

What are polar boiling points dependent on and why does it have a higher melting point?

Answer 3

Polar dependent molecules are dependent on the size of the molecule and the number of functional groups

Question 4

What is solubility with regards to homogenous mixtures and solutes and solvents?

Answer 4

Solubility refers to mix with a solvent to create a homogenous mixture. A solute can be soluble in wide ranges of solvents such as water or organic compounds.

Question 5

What happens when a water-soluble compound is placed in water? (4 points)

Answer 5

When a water-soluble organic compound is placed in the water it separates to mix with the water to form a homogenous mixture

The intermolecular forces (hydrogen bonding and dispersion) are overcome when water is added. Separation of the ethanol permits the formation of a homogenous solution with water.

Question 6

What are the properties of water-soluble organic compounds?

Answer 6

Organic water-soluble compound possesses small molecule size and possess one or more functional groups.

Question 7

With regards to the properties why cannot form a homogenous mixture with water?

Answer 7

Hence, the dispersion between functional groups is much stronger due to the larger electron cloud and greater polarity. The lack of intermolecular interactions limits the degree of mixing between insoluble organic compound and water.

Question 8

The difference between primary, secondary and tertiary alcohols

Answer 8

Primary - 1 - R group, secondary - 2 - R groups, tertiary - 3 - R groups attached.

Question 9

What are polyamides common in for application

Answer 9

Clothing, body armour, vehicle components, flame-resistant clothing, synthetic glass, fabrics and textiles.

Question 10

Proteins and there function

Answer 10

Enzymes: Catalysing chemical reactions in cells.
Peptide hormones: Sending chemical signals.
Receptors: Responding to chemical signals.
Antibodies: Killing invading microorganisms.
Structural: Providing structural support to cells and the body.
Transporters: Transporting materials in cells and the body.
