Hi,
How can you you determine whether a molecule is a BASE, ACID, NUCLEOPHILE,
ELECTROPHILE or a RADICAL from its skeletal structure.
Any help would be appreciated.
Thank you

Does it have a COOH group (or phenol)?

Does it have an NH2 group (although amides aren't best bases in the world)?

Does it have a pair of electrons it can donate (usually a lone pair on e.g. O or N)?

Does it have the ability to accept a pair of electrons (a delta+ C will do)?

Does it have a dot on the structure?

Nucleophiles have a positive partial charge on a C-Atom after an elimination of an atom (because of the segragation of the electron bonding), while an electrophile molecule has a double bond in as a rule to attract positive charges.

An acid molecule is capable of donating a proton, an H+ ion to be exact, while a base is accepting this proton.

Nucleophiles are electron pair donors (negative charge)
Electrophiles are electron pair acceptors (positive charge)
Bases are species that can accept a proton (e.g. -NH2)
Acids are species that can donate a proton (e.g. -COOH)
Free radical is a species with an unpaired electron

Hope this helps

Not always, e.g. NH3 is a nucleophile.
