Epoxidation of Alkenes Somewhere in one of your exams, you will see at least one question on epoxidation of alkenes. Quick tip: Before you start on alkenes, make sure you are good with alkanes, specifically the naming alkanes. The reaction:  What is epoxidation? An epoxide is a 3-membered ring containing two carbon atoms and one …

The Alkane Formula Before we can answer the question of what is the alkane formula, we have to ask ourselves what is an alkane. An alkane is a simple hydrocarbon containing carbon and hydrogen single bonded to each other, with a carbon backbone. Any molecule with this structure is going to have the formula CnHn+2, …

What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between an electronegative atom (one that has lone pair electrons) and a hydrogen atom bound to an electronegative atom. Because the electronegative atom has lone pair electrons and steals some electron density from other places, it takes on a partial negative charge, symbolized …

How many O3 resonance structures can be drawn? How many O3 resonance structures can be drawn? The answer is simple: two.  Briefly, if you follow the octet rule, you will see the oxygen atoms are connected linearly, where the central oxygen atom is always positively charged, and the terminal oxygen atoms are either negatively charged …
