Ethanoic acid reacts with ethanol in the presence of concentrated H₂SO₄ to form:
एथेनॉइक अम्ल (Ethanoic acid), सांद्र H₂SO₄ की उपस्थिति में एथेनॉल के साथ अभिक्रिया करके ______ बनाता है।
Detailed Solution & Logic
ethyl ethanoate/ एथिल एथेनोएट
📘 Explanation
When ethanoic acid reacts with ethanol in the presence of concentrated $H_2SO_4$, an ester called ethyl ethanoate is formed.
This reaction is known as esterification.
Reaction:
$CH_3COOH + C_2H_5OH \xrightarrow{conc.\ H_2SO_4} CH_3COOC_2H_5 + H_2O$
Here:
-
$CH_3COOH$ = Ethanoic acid
-
$C_2H_5OH$ = Ethanol
-
$CH_3COOC_2H_5$ = Ethyl ethanoate (an ester)
Concentrated $H_2SO_4$ acts as a catalyst and dehydrating agent, helping the reaction proceed faster.
🌟 Extra Facts
-
Esters usually have pleasant fruity smells, which is why they are used in perfumes and food flavorings.
-
The reverse reaction of esterification is called hydrolysis.
-
Esterification reactions were studied in detail by Hermann Emil Fischer and are sometimes called Fischer esterification.
-
Ethyl ethanoate is commonly used as a solvent in nail polish removers and paints.
📗 व्याख्या
जब एथेनॉइक अम्ल (Ethanoic acid), एथेनॉल (Ethanol) के साथ सांद्र $H_2SO_4$ की उपस्थिति में अभिक्रिया करता है, तो एथिल एथेनोएट (Ethyl ethanoate) नामक एस्टर बनता है।
इस अभिक्रिया को एस्टरीकरण (Esterification) कहते हैं।
अभिक्रिया:
$CH_3COOH + C_2H_5OH \xrightarrow{conc.\ H_2SO_4} CH_3COOC_2H_5 + H_2O$
जहाँ:
-
$CH_3COOH$ = एथेनॉइक अम्ल
-
$C_2H_5OH$ = एथेनॉल
-
$CH_3COOC_2H_5$ = एथिल एथेनोएट
यहाँ सांद्र $H_2SO_4$ उत्प्रेरक (catalyst) तथा जल हटाने वाला अभिकर्मक के रूप में कार्य करता है।
🌟 अतिरिक्त तथ्य
-
एस्टर सामान्यतः फलों जैसी सुगंध वाले होते हैं, इसलिए इन्हें परफ्यूम और फ्लेवरिंग एजेंट में प्रयोग किया जाता है।
-
एस्टरीकरण की उलटी अभिक्रिया को हाइड्रोलिसिस कहते हैं।
-
एस्टर अभिक्रियाओं का विस्तृत अध्ययन Hermann Emil Fischer ने किया था।
-
एथिल एथेनोएट का उपयोग नेल पॉलिश रिमूवर और पेंट सॉल्वेंट के रूप में भी किया जाता है।
