Alkenes are unsaturated hydrocarbons that have double bonds shared by two carbons. This means that not all of the carbon atom bonds are connected to hydrogen atoms. Therefore, more hydrogen atoms can be added to make the hydrocarbon saturated.

The word 'alkane' highlighted in a dictionary

Alkanes are saturated hydrocarbons. This means that each carbon atom is single-bonded to another carbon atom. Alkanes exist in straight chain, branched (isomeric), and cyclic forms. You can use a general formula to determine the specific formulas based on the number of carbon atoms. You can also easily name alkanes using the IUPAC standards.

Prozac, a green and white pill, that contains alkyl fluoride compounds

Also known as haloalkanes and alkyl halides, halogenoalkanes are organic compounds derived from alkanes, but with one hydrogen substituted for a halogen. They’re part of a much larger category known as halocarbons. Hydrocarbons with more than one hydrogen substituted by a halogen are called halogenated hydrocarbons. Halogenoalkanes have several commercial and industrial applications. For example, these compounds are commonly used…

Chemical elements. Background illustration on blackboard

Period 3 elements are those in the third row of the periodic table. The way period 3 elements form oxides, and how they react with other chemicals, is related to their positions in the periodic table. Furthermore, you can compare the relative atomic radius, ionisation energy, and electron affinity of the eight period 3 elements…

3D illustration of group 7(17), the halogens

The halogens are the six nonmetallic, highly reactive elements under Group VIIa (column 17) of the periodic table. They’re very strong oxidising agents, which means they take electrons from other substances. They’re also very reactive and usually form salts with Group 1a, i.e. the alkali metals. The name halogen literally means…

6 green cubes, each one bearing one of the alkaline earth metals

Alkaline earth metals, which are under Group 2 (the second column) of the periodic table, are highly reactive metals, though they’re not as reactive as the alkali metals. Their high reactivity is the main reason they aren’t found in a pure or elemental form in nature. Structurally speaking, these metals have two valence electrons in their outermost energy level…

3D render of elements from periodic table

Many elements were discovered long before the periodicity of elements was established by Dmitri Mendeleev in 1869. Mendeleev arranged the then-known elements in tabular form and discerned a pattern. With this, he was able to predict the existence of elements that had not yet been discovered…

A Level Chemistry Revision: Physical Chemistry – Equilibrium Constant Kp For Homogeneous Systems

Analysing the chemical reactions of gases in homogeneous systems may seem daunting at first. Unlike a liquid solution, the volume of gas isn’t constant, so determining the concentration of specific gas reactants is difficult when you base it on volume. This is where the concepts related to the equilibrium constant Kp for homogeneous systems of gases come into play. However,…
