Question

Match the descriptions below to the correct results from the tests above:

42. Conductivity of methanol
Litmus test of Methyl methanoate
Conductivity test of Methanoic acid
Litmus test of Methanoic acid
a) 1 - Positive; 2 - Red turns blue; 3 - No change; 4 - Blue turns red
b) 1 - Negative; 2 - Blue turns red; 3 - Positive; 4 - No change
c) 1 - Positive; 2 - No change; 3 - Negative; 4 - Red turns blue
d) 1 - Negative; 2 - Red turns blue; 3 - Positive; 4 - Blue turns red

Answer 1

The match for the descriptions would be Option D: 1 - Negative; 2 - Red turns blue; 3 - Positive; 4 - Blue turns red.

Step-by-step explanation:

The correct match for the descriptions would be Option D, where: 1 - Negative; 2 - Red turns blue; 3 - Positive; 4 - Blue turns red.

In the context of this question, methanol, methyl methanoate, and methanoic acid are all examples of substances that can exhibit different conductivity and litmus test results. Methanol is a polar compound and can conduct electricity, hence it shows positive conductivity. Methyl methanoate does not react with litmus paper, so there is no change in color. Methanoic acid, on the other hand, can conduct electricity and also turns blue litmus paper red.
