- Ans. This is because only those compounds which have hydrogen atoms can undergo aldol reaction. Ethanol possesses -hydrogen and undergoes aldol condensation. Methanal has no hydrogen atoms, hence does not undergo aldol condensation. Q. 21. Why does methanal undergoes Cannizaro’s rxn ? Ans. Because it does not possesses hydrogen atom.
- Hydrogen bonds occur between molecules that have a permanent net dipole resulting from hydrogen being covalently bonded to either fluorine, oxygen or nitrogen. For example, hydrogen bonds operate between water (H2O) molecules, ammonia (NH3)...
- We are being asked to determine which among the given molecules can form hydrogen bonds with other molecules of the same kind. Hydrogen Bond is the force that exists when H is directly connected to F, O, or N. Let’s draw the Lewis structure of each molecule and determine if there’s an H directly connected to F, O, or N in the molecule. a ...
