carboxylic Acid And Its Derivatives Flashcards
What are the observation when carboxylic acid reacts with carbonate
Bubbles of CO2
What are the physical properties of carboxylic acid?
1- forms hydrogen bonds with water so solvable in water
2- hydrogen bonds with another carboxylic acid and is called a DIMER and so higher melting point than other molecules with same Mr
Give me the carboxylic acid reactions with salt and
1- carboxylic acid reacts + salt = salt and hydrogen HCOOH + Na =. HCOONa + 1/2 H2
2- with oxides and hydroxides water is formed
3- with carbonates formes carbon dioxide and water
What do we called carboxylic=c when reacts with metals
MetaCarboxoate like magnesium ethanoate
Why does the carboxylic acid acts as an acid ?
1- the negative charge when it loses a proton becomes delocalized allowing it to be more stable in the pi bond too in the oxygen
What is the general formula of esters
R1COOR2
How do we form esters?
1-Ethanoic acid and ethanol make ester and water
What are the conditions for making an ester
1- strong acid like HCL or H2SO4
2- heating
How to name an ester
Start with the alcohol and ends with ate
Show esters hydrolysed in acidic conditions
Ester and water gives carboxylic acid and alcohol strong acid is needed and water
Show esters hydrolyzed in alkali conditions
1- NaOH and esters gives sodium ethanoate and alcohol( salt and alcohol)
2- non reversible
What is glycerol
Is propan123triol and can forms hydrogen bonds so solvable in water
What is the formula for vegetable oil
CH2OOCC6H13 x3 glycerol and decanoic acid
How do we get biodiesel
By reacting oils with ethanol with OH- catalyst which produces a methyl ester and glycerol
How do we get soap
Heating esters in alkaline condition with sodium hydroxide
What is acyl group
ROCl acyl chloride
How do we make acyl chloride
1- add SOCl2 or thionyl chloride
2- carboxylic acid + thionyl chloride = acyl chloride + sulfur dioxide + HCl
Naming acyl chloride
The carboxylic chain and chloride at the end and add oyl so ethanoyl chloride
What is acid anhydride
Where the water is removed from the 2 molecules of ethanoic acid
The reaction is reversible
What is the formula for the acid anhydride
RCOOCOR
How to make carboxylic acid from the last 2 derivatives
1- acid anhydride and water
2- acyl chloride and water
What does acyl chloride produce when reacts with water
Carboxylic acid and HCl
What does acid anhydride produce when reacting with water
2 molecules of carboxylic acid
What are the product when we react acid anhydride and alcohol
An ester and carboxylic acid
