Hydrogen Bonds

Hydrogen Bonds

Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....

Hydrogen Bonds

Hydrogen Bonds

A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Autoxidation of Ethers to Peroxides and Hydroperoxides

Autoxidation of Ethers to Peroxides and Hydroperoxides

Ethers represent a class of chemical compounds that become more dangerous with prolonged storage because they tend to form explosive peroxides when standing in the air. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly oxidize to form hydroperoxides and dialkyl peroxides.

Regioselectivity of Electrophilic Additions-Peroxide Effect

Regioselectivity of Electrophilic Additions-Peroxide Effect

In the presence of organic peroxides, the addition of hydrogen bromide to an alkene yields the isomer that is not predicted by Markovnikov’s rule. For example, the addition of hydrogen bromide to 2-methylpropene in the presence of peroxides gives 1-bromo-2-methylpropane. This addition reaction proceeds via a free radical mechanism, which reverses the regioselectivity. The free radical reaction mechanism involves three stages: initiation, propagation, and termination.

Area of Science:

Pediatric Gastroenterology
Toxicology

Background:

Constipation is a prevalent condition in children.
Hydrogen peroxide enemas are an infrequently reported home remedy for pediatric constipation.
This study investigates complications arising from such enemas.

Observation:

Two pediatric siblings presented with vomiting and bloody diarrhea shortly after receiving hydrogen peroxide enemas.
Clinical examinations and laboratory tests were largely unremarkable.
Computed tomography (CT) scans revealed significant mucosal thickening in the rectum and colon.

Findings:

The siblings' symptoms resolved with conservative management, including intravenous fluid replacement and bowel rest.
Literature review indicates that hydrogen peroxide enemas can lead to colitis, abdominal pain, and bloody diarrhea.
Documented complications range from bowel ulceration to necrosis and perforation, though fatalities are rare.

Implications:

This case underscores the potential severe gastrointestinal toxicity of hydrogen peroxide enemas in children.
Diagnostic modalities like CT scans are crucial for identifying enema-induced colitis.
There is a critical need for public health awareness campaigns to educate against the use of hazardous home remedies for constipation.
