It is known that the reactivity of the monomer is lower than it could be, since the contained ester group can react with the reactive, polymerizing chain end and stabilize it. It therefore reacts significantly slower than other molecules without ester group. [2] [6] ECC polymerizes also much slower than radical monomers. It is therefore the ...
The skin care obsession offers a window into the role social media plays in the lives of today’s youth and how it shapes the ideals and insecurities of girls in particular. Girls are ...
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′).

Girls are bombarded on social media with advice from influencers touting elaborate skin care routines with high-priced serums, mists and creams. Simple is best, dermatologists say. Many of the ...
Of course, Courtney was loving all the attention and clearly didn't care about her apparent fashion faux pas. With 2017 halfway over, we're only expecting more wardrobe malfunctions to come.

Unlike acid-catalyzed ester hydrolysis, it is not an equilibrium reaction and proceeds to completion. Hydroxide ion attacks the carbonyl carbon to give a tetrahedral intermediate, which then expels an alkoxide ion. The resulting carboxylic acid quickly protonates the alkoxide ion to give a carboxylate ion and an alcohol. [1]
