Alkenes

The first topic i will be doing about is on Chemistry for H2 students. The current subject is being taught at JC levels but it may still help for secondary school students who are studying on Organic Compounds.


Alkenes are unsaturated organic compounds containing at least one carbon-carbon double bond (denoted: C=C). Alkenes have a general formula of CnH2n. Alkenes undergo electrophilic addition as well as oxidation reactions. The term electrophilic addition indicates the addition of an electrophile (a molecule which is attracted to electrons). C=C bonds contain one pi (π) and one sigma (σ) bond. The C in alkenes undergo sp2 hybridisation. Alkenes may also display cis-trans isomerism.

Choose the ideal one for viewing. I just happened to find that inverting the colours using paint produces interesting results. =)
