Answer:
Saponification is a process of mixing triglycerides with potassium hydroxide (lye) in order to produce fatty acid and glycerol also known as soap.
During this experiment, many errors can occurs which are following;
- Incorrect measurement of both the salts that combine to form soap.
- The beaker and the stirrer has residue of some other chemical that gets mixed with two components and reacts.
- The two products are not mixed well or not long enough to reach the end product.
- The temperature is not favorable.
- The resting period is not calculated properly

Answer:
<em>The answer should have as many significant figures as the lowest number used in the multiplication, which is 1.2 . </em>
Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule 
there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule 
there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than .
In the molecule 
, there will be only hydrogen bonding. Hence, its boiling point is less than .
In the molecule 
, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.
< < <
