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।
