True or False Questions
According to the IUPAC rules for naming alcohols, the longest continuous chain of carbon atoms is numbered from the end farthest from the –OH group.
A primary (1°) alcohol is one in which the carbon atom with the OH group is attached to at least one other carbon atom.
The polar nature of alcohol molecules is particularly apparent in small molecules and reflected in physical and chemical properties of alcohols of low molar mass.
Hydrogen bonding greatly decreases the boiling points of alcohols compared to hydrocarbons of comparable molar mass.
While hydrocarbons are insoluble in water, alcohols with one to three carbon atoms are completely soluble
Primary and secondary alcohols are readily oxidized to aldehydes and ketones, respectively.
Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached, but is instead bonded to other carbon atoms.
Explanation / Answer
According to the IUPAC rules for naming alcohols, the longest continuous chain of carbon atoms is numbered from the end farthest from the –OH group. FALSE, you must include the nearest OH group
A primary (1°) alcohol is one in which the carbon atom with the OH group is attached to at least one other carbon atom. TRUE, which is one
The polar nature of alcohol molecules is particularly apparent in small molecules and reflected in physical and chemical properties of alcohols of low molar mass.FALSE, large molecules also classify on these physical /chemical properties
Hydrogen bonding greatly decreases the boiling points of alcohols compared to hydrocarbons of comparable molar mass. FALSE, it increases
While hydrocarbons are insoluble in water, alcohols with one to three carbon atoms are completely soluble. TRUE
Primary and secondary alcohols are readily oxidized to aldehydes and ketones, respectively. TRUE
Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached, but is instead bonded to other carbon atoms TRUE
