Question: Identify the type of the following reaction of carbon compounds. (A) \( C{H_3} - C{H_2} - C{H_2} -...

Identify the type of the following reaction of carbon compounds.
(A) CH3−CH2−CH2−OH→CH3−CH2−COOHC{H_3} - C{H_2} - C{H_2} - OH \to C{H_3} - C{H_2} - COOH
(B) CH3−CH2−CH3→3CO2+4H2OC{H_3} - C{H_2} - C{H_3} \to 3C{O_2} + 4{H_2}O
(C) CH3−CH=CH−CH3+Br2→CH3−CHBr−CHBr−CH3C{H_3} - CH = CH - C{H_3} + B{r_2} \to C{H_3} - CHBr - CHBr - C{H_3}
(D) CH3−CH3+Cl2→CH3−CH2−Cl+HClC{H_3} - C{H_3} + C{l_2} \to C{H_3} - C{H_2} - Cl + HCl
(E) CH3−CH2−CH2−CH2−OH→CH3−CH2−CH=CH2+H2OC{H_3} - C{H_2} - C{H_2} - C{H_2} - OH \to C{H_3} - C{H_2} - CH = C{H_2} + {H_2}O
(F) CH3−CH2−COOH→CH3−CH2−COO−Na++H2OC{H_3} - C{H_2} - COOH \to C{H_3} - C{H_2} - CO{O^ - }N{a^ + } + {H_2}O

Explanation

Solution

There are many different reactions present in the above question such as oxidation reaction, substitution reaction, addition reaction and many more. First acid base reaction takes place. In the case of rings there are two reactions which are ring expansion and ring contraction. Then rearrangement is done.

Complete answer:
(a)This reaction is an oxidation reaction. We can clearly see that alcohol gets converted to carboxylic acid. The product formed is propanoic acid.
Oxidation reaction: When there is a gain of oxygen or loss of electrons takes place then this reaction is known as oxidation reaction.
(b)This reaction is a combustion reaction. The products formed are carbon-dioxide and water.
Combustion reaction: A combustion reaction is a reaction when substance reacts with oxygen to release energy or to form carbon-dioxide and water.
(c)This reaction is an additional reaction. The product formed is 2,32,3 -dibromobutane.
Addition reaction: A reaction in which one molecule combines with another to form a larger molecule with no by product.
(d)This reaction is a substitution reaction. We can clearly see that hydrogen is replaced by chlorine. The product formed is chloroethane and hydrochloric acid.
Substitution reaction: When one element replaces or substitutes another element, then it is called substitution reaction.
(e)This reaction is an elimination (dehydration) reaction. The product formed is butane and water.
Elimination reaction: When the elimination of an element takes place in the reaction, then it is known as elimination reaction.
(f)This reaction is an acid-base (neutralization) reaction. The product formed is sodium salt of carboxylic acid.
Acid-base reaction: The reaction in which the exchange of H+{H^ + } ions takes place is called acid-base reaction.

Note:
As we talk about the basic approach of organic reactions we see that after the rearrangement of ring expansion reaction or ring contraction reaction intermolecular reaction or intramolecular reaction takes place. Intermolecular reactions are faster than the intramolecular reactions.
