IIT/JEE Chemistry Practice #32: Protonation States and pKa
Practice REAL problems from actual past IIT/JEE exams with Professor Dave!
Professor Dave Explains
Practice Problem: Conversion of trans-2-butene to cis-2-butene
How can we go from one type of alkene to another? In three steps precisely? Use the reactions you know and figure it out! (Hint: Think about addition reactions, elimination reactions, and hydrogenations!)

Practice Problem: E2 on Cyclic Systems and Cyclohexane Chairs
For this one we will want to recall some of the rules about doing E2 on a cyclohexane ring, as well as the relative stabilities of cyclohexane chairs. Combining concepts! Predicting kinetics!
Professor Dave Explains
Practice Problem: Site of Protonation on a Weak Base
For this one we will need to understand the basics about Bronsted-Lowry acid-base reactions, and we also should be able to gauge the stability of various potential conjugate bases.
Professor Dave Explains
Practice Problem: Analyzing Acid-Base Equilibria
Acids! Bases! Conjugate acids! Conjugate bases! We definitely have to be able to label such things, and we should also know how to state which direction in an acid-base equilibrium is preferred. To do this we should know how to tell...

What Is The Bronsted Lowry Theory
Have you ever head of the Bronsted Lowry Theory of acids and bases, an essential theory of Chemistry? It helps you fill the gaps in the Arrhenius theory. This education video by the Virtual School will teach you about: - Testing acids -...

Practice Problem: Reaction of a Terminal Alkyne
We've got a terminal alkyne, and we're gonna do some stuff to it. What will we get? What's that Grignard reagent gonna do? Be careful!
Professor Dave Explains
Practice Problem: Crossed Aldol Products
Enolate chemistry is tricky business! You might get more products than you think. Give this one a shot.

What Is The Smallest Particle We Know?
We have built beautiful particle accelerators in the search for particles that are even more elementary than electrons, protons, and neutrons. The accelerators smash subatomic particles at enormous speeds, which causes them to shatter...

Practice-Problem: Two-Reaction Pathway
This time we have a starting material, and we are gonna do just two reactions. But it's a little tricky! See if you can figure it out.

Practice Problem: Drawing Substitution and Elimination Products (SN1/SN2/E1/E2)
I know you guys are dying for more practice choosing between SN1/SN2/E1/E2 mechanisms, so hopefully this one helps a little. Make sure to look at all the factors we talked about in my tutorial on this topic!

Practice Problem: Nuclear Reactions
We've learned about all the different types of nuclear reactions that can occur, so given this word problem, can you find the missing nuclide?
Professor Dave Explains
Practice Problem: Assigning Molecular Structure From an NMR Spectrum
For this one we need to be able to interpret NMR data in order to arrive at the correct molecular structure based on an empirical formula. It's not as hard as it sounds!
