fats and oils

Question 1

What makes fats and oils?

Answer 1

= glycerol (alcohol)
= fatty acid (cooh acid)
= produces an ester that makes fats and oils

Question 2

What is the IPUAC name for glycerol?

Answer 2

= propane-1-2-3-triol
= so 2 OH groups

Question 3

What can fatty acids either be?

Answer 3

• saturated- singular c-c bonds
  = unsaturated c=c bonds
  =

Question 4

What are fatty acids with more than 1 double bond called?

Answer 4

= polyunsaturated

Question 5

What group is an oil in?

Answer 5

= ester group
=has double bonds in the hydrocarbon chains, unsaturated

Question 6

What are vegetable oils?

Answer 6

= they have unsaturated hydrocarbon chains
= not straight
= weeaker vanderwall foces, lower contact, less surface area for the formation of these
= lower melting points liquids at room temperatire

Question 7

What are fats?

Answer 7

= esters with saturated hydrocarbon chains

Question 8

What are animal fats?

Answer 8

= saturated hydrocarbon chains
= straight and uniformed, so stronger vanderwall forces, closer contact, pack together, higher melting points, solid at room temperature
