Question

define the following terms
a. Catenation b. Hydrogeneration
c.esterification​

Answer 1

Answer:

a) Catenation:  Carbon has the unique ability to form bonds with other atoms of carbon,  giving  rise  to  large  molecules.  This  property  is  called catenation.

b) Hydrogenation:  An example of an alkene addition reaction is a process called hydrogenation.In a hydrogenation reaction, two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane.

c) Esterification:  Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials, and often have a characteristic pleasant, fruity odor. This leads to their extensive use in the fragrance and flavour industry. Esterification is a reversible reaction.

Example:

H3C-COOH + HO-CH2-CH3     →     H3C-COO-CH2-CH3 + H2O

Answer 2

catenation- It is the ability of an elememt ,to combine with the same species of its atom covalently to form rings and chain. carbon has hightest catenation power in periodic table since it can form large amount of compound.

hydrogenation- It is a chemical reaction between hydrogen and a compound or element in presence of catalyst.

estrification- Estrification is when an alcohol and a carboxylic acid react together (with sulphuric acid as a catalyst) to form an ester.
