CUET Preparation Today
Two molecules of an aldehyde or ketone containing α- hydrogen atom, combine itself in the presence of dilute alkali to form β-hydroxyaldehyde or β-hydroxyketone.
This reaction is called aldol condensation after the name of the product which contains both aldehyde (al) and a hydroxy (ol) group. Similar condensation of two molecules of ketones ( α- hydrogen) is also considered as aldol condensation although the product in this case contains a keto and hydroxy group rather than an aldehyde group. |
| Condensation reaction is the reverse of which of the following reaction? |
Lock and key hypothesis Oxidation Hydrolysis Glycogen formation |
| Hydrolysis |
| This reaction example is the reverse of hydrolysis, which splits a chemical entity into two parts through action from the polar water molecule, which itself splits into hydroxide and hydrogen ions. |
