You can identify a compound to be an alcohol when it has a hydrocarbon chain and a hydroxyl functional group or -OH group. Also, from the name, you can tell that it is an alcohol is the suffix -ol is present. Examples are ethanol and methanol. Alcohol is any organic substance that contains an hydroxyl group bonded to a carbon atom that is saturated. Alcohols can be classified as primary, secondary or tertiary depending on where the hydroxyl functional group is attached in the hydrocarbon chain. It is a primary alcohol when OH is attached to the first carbon atom. Secondary alcohol, and tertiary alcohols has a general formula CHROH and CR2OH, respectively where R represents a hydrocarbon chain.<span />

Answer:
d. ii.
Explanation:
Hello!
In this case, according to the displayed decimal placed by each balance, we can notice that:
i. Displays 1 decimal place.
ii. Displays 2 decimal places.
iii. Displays 4 decimal places.
iv. Displays 3 decimal places.
Thus, since the measured-out masses have two decimal places each, we infer that the used balance was d. ii as it displays two decimal places.
