What effect would the contamination by the following impurities have on the melting point of benzoic acid?
a. sand
b. benzoin
c. broken glass
d. pieces of insoluble cork
e. water
f. acetylsalicylic acid
Solution
There would be no effect on melting point of benzene of
Sand
Broken glass
And pieces of insoluble cork as they can no way interact chemically.
In case of benzoin and water, due to significant hydrogen bonding, melting point of benzene increases
For the case of acetylsalicylic acid, it does not increase because the acid hardly interact and form bond due to its large size and stearic hindrance.
