imide

Amide but with one more carbonyl group. It is not basic and if the nitrogen is bonded to H, even sodium hydroxide can deprotonate it.
Imides have very low pKa values, and is not basic at all.

methyl orange

A pH indicator (most commonly) used in acidic conditions.
In acidic conditions methyl orange is red but in neutral / basic conditions it is yellow.

chemophobia

The fear of chemistry/ chemicals. The actual truth is that chemicals are everywhere, including water. Unfortunately, people make 'chemical-free' stuffs (which is wrong). This problem, therefore, should be fixed.
Just see how strong your chemophobia is.
Do you know that dihydrogen monoxide is now found in every water source? Its gas and solid state can burn people! And it is the main component of acid rain! You want to ban it?
Actually it is water.

The dose makes the poison

Everything in the world is harmful if in large amounts, and this includes all-natural fruits, water, etc. , because the dose (amount) makes the poison (lethal).
Ad: "No artificial sweeteners, all-natural! Detox drink"
Me: "The dose makes the poison, do you know that everything can be toxic?"

ketone

An organic functional group with a carbonyl in the middle and other groups on the 2 other sides (usually represented as R and R')
The most common ketone is acetone, which is used in fingernail polishes.

Cyclopentadiene

An hydrocarbon compound that is basically violating being a hydrocarbon. Its pKa value is only 16, making it as acidic as water.
Its structure is a cyclopentane ring with 2 double bonds.
The reason for cyclopentadiene to be such acidic is because of its ionic structure. It has an aromatic anionic structure, making it extremely stable.

Tetrahydrofuran

Tetrahydrofuran (THF) is a cyclic ether (heterocyclic compound) with a 5-member ring and an oxygen atom inside. Its formula is C4H8O
We need ionic compounds for this reaction! Use tetrahydrofuran or it won't dissolve!
