Organic chemistry test Flashcards
what is classified as “organic”?
consists of carbon and hydrogen, anything that is living or was once living
what is alkane
a hydrocarbon with single bonds
what is alkene
a hydrocarbon with at least one double bond
what is alkyne
a hydrocarbon with at least one triple bond
what are the prefixes?
methane, eth, prop, but, pen, hex, kept, oct, non, deca
what does saturated mean?
maximum amount of hydrogen, refers to the general formula
what to think when you’re naming
what am I naming, how many are there, where are they?
how to name the shape ones
cyclo- ___ ane/ene/yne
what is a homologous series
a series of compounds with the same functional group. they have similar chemical properties, such as methane, ethane ect.
how does boiling point change with the length of the chain?
it increases as the chain gets longer
why does the boiling point increase with the amount of carbon?
the dispersion forces become larger with larger molecule sizes.
solubility rules?
polar dissolves polar, vice versa
how does volatility work?
it becomes more volatile as the boiling point goes down. this is bc as the compound becomes easier to boil, it becomes vapours easily as well.
what are aldehydes?
double bond “o” at the end, to form -CHO (HO is used to show it isn’t an alcohol)
what is the naming rule for aldehydes?
suffix of “al”, like methanal, ethenal, propanal
what are ketones?
a double bond O in the middle of a chain.
how are ketones named?
suffix of “none”, no such thing as methanone or ethanone, propane and butane don’t need specifics on where the bond is.
what are carboxylic acids?
also known as alkanoic acid, double bond O and OH, written as -COOH
how to name carboxylic acids?
suffix of (-oic acid) carboxylic acids can only be on the end, in the case where theyre on both ends, its named as (-dioic acid)
what is the order of priority with naming?
hydroxyls, alkanes, alkynes, alkenes, hallogens.
