QUESTION:
In the following acid–base reactions,
1. determine which species are acting as electrophiles (acids) and which are acting as nucleophiles (bases).
2. use the curved-arrow formalism to show the movement of electron pairs in these reactions, as well as the imaginary movement in the resonance hybrids of the products.
3. indicate which reactions are best termed Brønsted–Lowry acid–base reactions.
ANSWER:
Solution:
Step 1
Electrophiles:-Electrophiles are the electron loving species. A molecule or ion that accepts a pair of electrons to make a new covalent bond is called an electrophile .
Nucleophiles:-Nucleophiles are the nucleus loving species. A molecule or ion that donates a pair of electrons to form a new covalent bond is called a nucleophile.
In this acid base reaction, proton transferred from HCl to C=O group of CH3CHO . Therefore HCl is an electrophile and CH3CHO is a nucleophile.
