Properties of Functional Groups Flashcards
True or False; alcohols are polar
True
True or False; alcohols have low boiling points
False (They have higher boiling points than hydrocarbons
of similar molar mass)
True or False; the boiling point of alcohols increases as the length of carbon chain
and OH groups increase
True
Alcohols with one to four carbons are _____ in water.
Soluble
Alcohols with five to six carbons are _____ in water.
Moderately soluble
Alcohols with seven carbons or more are _____ in water.
Nearly insoluble
True or False; Diols and triols are more water
soluble than alcohols with only a
single hydroxyl group
True
True or False; All functional groups are polar except for Thiols
True
True or False; Ethers have lower boiling points than alcohols of
similar molar mass due to lack of hydrogen
bonding.
True
True or False; Ethers have lower boiling point than alkanes
False
True or False; Ethers are less soluble in water and more soluble in organic solvents
True
True or False; Thiols have high solubility in water
False (They have lower solubility)
True or False; Ethers have lower boiling points than alkanes of similar molar mass.
False (They have higher)
True or False; Solubility falls off dramatically as the carbon content of the carboxylic acid increases.
True
True or False; Carboxylic acids have significantly higher
boiling points than other types of organic
compounds of comparable molecular
weight
True
True or False; Boiling point of esters is higher than alcohol and carboxylic acid.
False (It is lower)
True or False; Aldehydes boil at higher temperatures than alcohol.
False eyyy (They boil at lower temperatures)
True or False; Ketones boil at lower temperatures than alcohol of similar molar mass because of weaker forces.
True
True or False; In amines, boiling point decreases in the absence of hydrogens. The boiling point is highest in primary amines.
Korique
True or False; Amines boil at higher boiling points than alkanes and ethers.
Trueeee
True or False; Amides boil at lower temperature than amine and other hydrocarbon.
False (They boil at higher)
True or False; generally, water solubility decreases as the length of the hydrocarbon portion increases
True
Only how many carbons in aldehydes can guarantee solubility in water?
Five or fewer
Which functional groups generally have low solubility in water?
Ethers and thiols
Which functional groups generally have low solubility in water?
Ethers and thiols
Which part of the structure of functional groups are water-fearing or hydrophobic?
Hydrocarbon part
