carboxylic acids

what do carboxylic acids contain

the caeboxyl functional group - COOH

how are they names

find the longest alkane chain and take of the e and add -oic acid

where is carboxylic group always found

at the end of the molecule

what are the greek letters used for in carboxyic acids

they refelct the carbons as the move away from the functional group cooh

describe carboxilic acids as acids, what do they do in water

they are weak acids, they dissasosiate in water into carboxylate and h ions

what are the phisical proerties of caeboxylic acids

H3C that hydrophobic and non polar, O—OH that hydrophillic and polar making it reactive

what does the arrangement of hydrogen bond donors and acceptors allow for

the formation of dimers (2 identical smaller units joined together)

comare the acidity od carboxylic acids

significantly more acidic than alcohols

what are the 2 factors effecting acidity

the strenght of the bond being broken and th stability of the resulting ion

what do alkyl groups do to electrons what does this result in

push themselves away from electrons resulting in hyperconjigation increacing the negitive charge on the carboxylate group destabalising the ion

how can esters be made from carboxylic acids

the carboxylic acids are reacted with alcohol

how can carboxilic acids create amides

through a condensation reaction - also can form peptide bonds = protiens
