If you have studied the chemistry of fats can you identify the end arrangement found in fatty acids as well as amino acids? What

White raven [17]

Answers:
1) - COOH
2) carboxyl group

The organic acids contain the carboxyl group: - COOH.

Fats are structures composed by fatty acids. Fatty acids are long aliphatic chains with a carboxyl group at the end.

Aminoacids are chains that contains amine group (NH2) at one end and the carboxyl group at the other end.

Then both aminoacids and fatty acids contain the carboxyl group (-COOH) at one end.

For each of the esters provided, identify the alcohol and the carboxylic acid that reacted.

Veronika [31]

Answer:

52. The alcohol USED => methanol, CH3OH

The carboxylic acid USED => propanoic acid, CH3CH2COOH.

53. The alcohol USED => Ethanol, CH2CH3OH

The carboxylic acid USED => Formic acid, HCOOH.

Explanation:

52. To obtain Methyl propanoate, CH3CH2COOCH3, we simply react propanoic, CH3CH2COOH and methanol, CH3OH together as shown below:

CH3CH2COOH + CH3OH —> CH3CH2COOCH3 + H2O

The alcohol used: methanol, CH3OH

The carboxylic acid used: propanoic acid, CH3CH2COOH.

53. To obtain Ethyl methanoate, HCOOCH2CH3, we simply react

Formic acid, HCOOH and ethanol, CH3CH2OH together as show below:

HCOOH + CH3CH2OH —> HCOOCH2CH3 + H2O

The alcohol USED => Ethanol, CH2CH3OH

The carboxylic acid USED => Formic acid, HCOOH.

Consider the chemical reaction in equilibrium.

Zarrin [17]

This is an application of Le Chatlier's principle: What happens when we add a reagent to one side of an equation? The reaction will shift to the other side. So heat is a reactant and we're adding more of it, the reaction must therefore, shift to the right ( or the products side).
