What is a functional group 4 Hydroxyacetophenone?

Description. 4′-hydroxyacetophenone, also known as (4-hydroxyphenyl)ethan-1-one or 4-acetylphenol, is a member of the class of compounds known as alkyl-phenylketones. Alkyl-phenylketones are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group.

What does a negative pKa mean?

The more more negative a pka is, the stronger the acid. That’s more or less it, without math. Negative pka’s are really strong acids. (The math allows them to be negative, because the pka is basically an exponent.

Is pKa always positive?

This experimental parameter is called “the pKa”. The pKa measures how tightly a proton is held by a Bronsted acid. A pKa may be a small, negative number, such as -3 or -5. The higher the pKa of a Bronsted acid, the more tightly the proton is held, and the less easily the proton is given up.

What is NH3 in chemistry?

Ammonia is a colorless inorganic compound of nitrogen and hydrogen with the formula NH3, usually in gaseous form with a characteristic pungent odor. Ammonia is irritating to the skin, eyes, nose, throat, and lungs. It is essential for many biological processes and has various industrial applications.
