Organic Chemistry formulas: Alkanes, alkenes and alkynes are three classes belonging to the hydrocarbon homologues series. These are organic compounds that are composed of carbon and hydrogen as their name implies. Alkanes have only single bonds, and are therefore saturated hydrocarbons. Their formula is CnH2n+2. Thus, for example four carbon alkane will be C4H 2(4)+2 = C4H10 Alkenes are unsaturated because they have a double bond. Their formula is CnH2n. Thus, for example fo

Oftentimes, when we do organic chemistry problems we must determine what kind of reaction we have. For the SN1, SN2, E1 and E2, our substrat

It is very important to know how to draw arrows right for your organic chemistry class. Arrows are the backbone of mechanisms and show us exactly how reactions happen. The tail of an arrow represents where electrons are coming from. Therefore, we must always draw an arrow from something that has electrons. In most cases, it is an element with a lone pair of electrons or a double bond. Never draw an arrow from Hydrogen (many students often make this mistake). Hydrogen does not

In organic chemistry, we are often asked to rank the triple, double and single bonds in terms of their strength and length. In a triple bond , 3 pairs of electrons are shared, while in a double bond only 2 pairs are shared and in a single bond, one pair electrons is shared. Therefore it takes more energy to break a triple bond and thus, triple bond is the strongest, followed by the double bond, and single bond. The order of length is opposite of that of strength, the triple

Ketone and aldehydes are functional groups that organic compounds have. A ketone is C=O that is connected to a carbon on both sides. Therefore it is always found inside a chain and never at the end. Aldehyde, on the other hand is C=O that is connected to a carbon on one side and hydrogen on another. Therefore, aldehydes are found at the end of chains.

The question about saturation of molecules is asked very often on organic chemistry exams. It is a very easy one to answer! A saturated molecule has all single bonds. An unsaturated molecule has double bonds or triple bonds. Therefore, alkanes are always saturated while alkenes and alkynes are always unsaturated. Saturated hydrocarbons, due to the lack of double and triple bonds, can pack very well. That is why butter is solid at room temperature (since it is made of saturate

Here are the top five reasons for loving your organic chemistry class. 1. No Math! Gone are the days of graphing calculators and 10 digit n

Taking Organic Chemistry during summer is sometimes a tough task but oftentime rewarding one. Most of the students who you will find taking the summer class with you, are either Post-Bac or undergraduate students retaking the class. If you decide to take organic chemistry during the summer, you have to be prepared to work hard since the semester goes by in a matter of weeks. My students started second semester on monday and are taking their exam this thursday already (a week
