question 24

Short Answer

Table 7.5
The following results were obtained from a use- dilution test of two disinfectants.
Cultures were inoculated into tubes containing varying concentrations of the disinfectants, incubated for 10 min. at 20°C, and then transferred to growth media without disinfectant. (+ = growth; - = no growth)

-In Table 7.5, which disinfectant is most effective? Against which group of bacteria is Disinfectant A most effective?

Definitions:

π Network

A collection of π bonds (p-orbital overlap contributing to bonding in molecules) interconnected in a molecule, fundamental to the structure and stability of aromatic compounds.

Acidic H Atoms

Hydrogen atoms in a molecule that can be donated as protons during an acid-base reaction.

AntiAromatic

Describes molecules that do not follow Hückel's rule, often destabilized and non-planar, lacking aromatic stabilization.

NonAromatic

A classification for organic compounds that do not meet the criteria for aromaticity, lacking a conjugated system of pi electrons.
