WebJ shows the following properties: its molecular formula is C 4 H 8 O 2, it is neutral, it reacts with sodium metal, it reacts with Fehling's solution, it does not react with aqueous … WebA Correct answer: A Explanation: For a compound to be considered aromatic, it must be flat, cyclic, and conjugated and it must obey Huckel's rule. Huckel's rule states that an aromatic compound must have pi electrons in the overlapping p orbitals in order to be aromatic (n in this formula represents any integer).

The other is amide-like and is deactivated by the adjacent carbonyl group. The rate at which these imine-like compounds are formed is generally greatest near a pH of 5, and drops at higher and lower pH's.
WebThe mean duration of the first stage in the control group was 215 minutes, compared with 165 minutes in the study group, representing a decrease of 23.3% (P = 0.001). There were no significant changes in the duration of the second ( P = 0.063) or third ( P = 0.0418) stages of labor, and no significant differences in blood loss or Apgar scores. WebFunctional groups are specific substituents or moieties, composed of an atom or a group of atoms, within molecules that possess similar chemical properties whenever it occurs in different compounds. Functional groups determine the characteristic physical, chemical and biological properties of a molecule. Implicit and Explicit Atoms
WebA functional group is any collection of atoms and/or bonds with certain characteristic chemical reactions. We have already seen two functional groups: the C–C double bond and the C–C triple bond. They undergo certain characteristic chemical reactions — for example, the addition of a halogen across the multiple bond.
