What are hydrogen bond-donor and acceptor in acetic acid molecules?
The C=O (the O atom) carries a slightly negative charge so it attracts the H ion from another molecule. the OH part of the COOH is the H that bonds to the O atom of another molecule.
thanks for the help
To determine the hydrogen bond donor and acceptor in acetic acid (CH3COOH) molecules, we need to examine the structure of the molecule and identify the atoms involved in hydrogen bonding.
In acetic acid, there are two possible hydrogen bond donor sites and one hydrogen bond acceptor site. The oxygen atoms (O) in the carboxyl group (-COOH) act as the hydrogen bond acceptors. They have pairs of lone electrons that can form a partial negative charge, making them attractive to hydrogen (H) atoms.
On the other hand, the hydrogen atoms bonded directly to these oxygen atoms are the hydrogen bond donors in acetic acid. These hydrogen atoms have a partial positive charge because their electrons are being shared with the oxygen atom.
Overall, in acetic acid, the oxygen atoms (O) act as the hydrogen bond acceptors, while the hydrogen atoms bonded to these oxygen atoms act as the hydrogen bond donors.
To visualize this, you can refer to the Lewis structure or molecular diagram of acetic acid, where the hydrogen bond donors and acceptors are often represented using dashed lines to indicate hydrogen bonding interactions.
