Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O

Explanation:

Dehydration

In chemistry, a dehydration reaction is one that involves the loss of water. In organic synthesis, where an acid is often used as a catalyst, there are numerous examples of dehydration reactions: Conversion of alcohols to ethers: 2 R-OH → R-O-R + H2O Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O Conversion of amides to nitriles: RCONH2 → R-CN + H2O

zalisa [80]

The anterior fontanel is a diamond-shaped area where the frontal and parietal bones meet. It closes between 12 and 18 months of age. Vigorous crying may cause the fontanel to bulge, which is a normal finding. A nurse is performing an assessment on a postterm infant.

<h3>What is anterior fontanel?</h3>
  • This is the junction where the 2 frontal and 2 parietal bones meet. The anterior fontanelle stays soft until about 18 months to 2 years of age. Doctors can consider if there is increased intracranial pressure by touching the anterior fontanelle.
  • The fontanel can broaden in the first few months of life,18 and the median age of closure is 13.8 months. By three months of age, the anterior fontanel is secured in 1 percent of infants; by 12 months, it is closed in 38 percent; and by 24 months, it is closed in 96 percent.
  • The fontanelle allows the skull to distort during birth to facilitate its passage through the birth canal and for expansion of the brain after birth. Skull at birth, showing frontal and occipital fonticuli. The anterior fontanelle normally closes between the periods of 12 and 18 months.
