this is all regarding organic chemistry...

can someone explain how to tell if something is a nucleophile or an electrohpile and please give examples of each?

also, when naming with iupac names such as 4,3-methylpentane (I randomly made this name up), how do you know what time name then and if the name is right?

Expert Solution

A nucleophile is a reactant that provides a pair of electrons to form a new covalent bond.In other words, Nucleophiles are Lewis bases.When the nucleophile donates a pair of electrons to a proton, it’s called a Brønsted base, or simply, “base”. Examples -

An electrophile is a species that accepts a pair of electrons to form a new covalent bond.In other words, Electrophiles are Lewis acids.An electrophile that accepts an electron pair at hydrogen is called a Brønsted acid, or just “acid”.Here are some examples of Lewis acids -

Electron richness (or poorness) of an atom (or molecule) determines its nucleophilicity or electrophilicity, which in turn determines its reactivity.

To get the right IUPAC names you have to follow the rules and assumptions of the IUPAC nomenclature.

In your random name, 4 and 3 defines two positions on a pentane ring with two methyl groups attached so correct name should be-

4,3-dimethylpentane

We can all think of someone that has done something incredibly stupid when they are intoxicated. Do you have sympathy for intoxicated people who make agreements? Should the law ever let them back out of deals when they sober up? After all, no one forced them to get drunk. The law in contracts, as it currently stands is that when one party is so intoxicated that he cannot understand the nature and consequences of the transaction, the contract is voidable....
