COVALENT BONDING - DOUBLE BONDS. This page explains how double covalent bonds arise. It starts with a simple picture of double covalent bonding, and then takes a more sophisticated view of the bonding in ethene.
An explanation of the bonding in methane and ethane, including a simple view of hybridisation.
such as ethene, propene and the rest. It deals with their formulae and isomerism, their physical properties, and an introduction to their chemical reactivity. What are alkenes? Formulae. Alkenes are a family of hydrocarbons (compounds containing carbon and hydrogen only) containing a carbon-carbon double bond.
An introduction to the arrangement of electrons in atoms - leading to the modern electronic structures of carbon and hydrogen. Bonding in methane . . . Covers bonding in methane and ethane, including a simple look at hybridisation. Bonding in ethene . . . Covers bonding in ethene, including a simple look at hybridisation.
Chemguide – answers. BONDING IN ETHENE. 1. a) 1s22s22px. 12py. 1. b) One of the 2s electrons is promoted by moving it into the slightly higher energy 2pz orbital to give the structure 1s22s12px. 12py. 12pz. 1. Or with a diagram: c) In the case of ethene, each carbon atom has to join to three other things (2 hydrogen
If you have already read the whole of the covalent bonding page referred to in learning outcome 3(b), you will recognise the bit about methane. Methane isn't specifically mentioned by the syllabus, but you must be sure that you understand that before you go on to the ethane at the bottom of the page. Don't go on to ethene
This is all exactly the same as happens in ethene. The difference in benzene is that each carbon atom is joined to two other similar carbon atoms instead of just one. Each carbon atom uses the sp2 hybrids to form sigma bonds with two other carbons and one hydrogen atom. The next diagram shows the sigma bonds formed
At a simple level, you will have drawn ethene showing two bonds between the carbon atoms. Ethene is built from hydrogen atoms (1s1) and carbon atoms (1s22s22px12py1). These are sigma bonds - just like those formed by end-to-end overlap of atomic orbitals in, say, ethane.
To understand ethene you also have to understand orbitals and the bonding in methane - sorry, there are no short-cuts!

Chemguide – questions. BONDING IN ETHENE. 1. a) Write the electronic structure (using s and p notation) of the carbon atom in its ground. (unexcited) state. b) When carbon forms its bonds in ethene, an electron on each carbon atom has to be promoted. Explain what this means, using a diagram if you wish.
