Give an example of how a functional group can affect the properties of an organic compound.

The functional group can affect the chemical properties and physical properties. Like CH3CH3 and CH3CH2OH. The first one is gas and second one is liquid. The first one is not easy to react with others while the second one is.

The correct option is C) milligram, centigram, decigram

Explanation:

The metric system of units goes by the units of tens.  It is one of the most widely used systems for measurements.

One milligram equals to 1/1000 of a gram.

The centigram equals to 1/100 of a gram. Hence, it is larger than the milligram.

The decigram equals 1/10 of a gram. Hence, it is larger than centigram and milligram.

Hence, the correct option would be C) milligram, centigram, decigram.
