New cards
Carboxylic acids
most important organic acids, week acids
2
New cards
What makes it acid
the H+-ion
3
New cards

what makes the carboxylic acids hydrofile

dubble bonded to a oxygen (keeps the valenceshell) and one of the oxygens are conected to a hydro

4
New cards
-COOH-
carboxyl group, known in carboxylic acids
5
New cards
Maursyre
methanoic acids
6
New cards

Simplest carboxylic acid

methanoic acid. "maursyre", occurs if you have been biten by a ant or touched brennesle. +

<p>methanoic acid. &quot;maursyre&quot;, occurs if you have been biten by a ant or touched brennesle. +</p>
7
New cards
If wine is out for too long it creats
Acitic acid/eddiksyre
8
New cards
systematic name for Acitic acid/eddiksyre
etanoic acid, contains equally much carbons like etane.
9
New cards
Carbonxylic acids with more than 3 C-atoms
called fatty acids
10
New cards

Carboxylic acids compared to the unorganic acids

it is weak

11
New cards
The reason carbonxylic acid is weak
for example, the ethanoic acid disolves in water it separates (dissociate) into ions
12
New cards

Ethanoic acid dissociation into ions

gives little H+-ion in a water solution.

13
New cards

Ethanoic acid disolved in water, formula

<ul><li><p></p></li></ul>
14
New cards
Reason why the carboxylic acid is sour
innehlder oksoniumioner H3O+-ioner = H+, the more there are -> more acidic
15
New cards
What kind of acid lacticacid(melkesyre) is
a carboxylic acid, but also contains hydroxl groups -> a hydroxide acid.
16
New cards
lacticacid in the body
made in the muscle and surface of the skin
17
New cards
lacticcid in the industry
milkproducts,
18
New cards
lacticacids purpose on the skin
makes a sour enviorments to protect from harmfull bacteria.
19
New cards

What makes our musles sore

lacticacid, made when the muscles work without oxygen -> made when "nedbrytning av glukose" and makes the muscle stiff.

New cards
Estere use
fragrance from fruit and flowers in parfums and candy.
24
New cards
Formation of Ester compounds
condencation; reaction of carboxylic acids and alchols.
