WebSo, let's start this video by taking this Lewis dot structure and turning into a bond line structure. If you look at the drawing on the left it implies that these three carbons are in a perfectly straight line but the drawing on the right does a little bit better job of showing what the molecule looks like in reality. Cracking is important for two main reasons: 1. It helps to match the supply of fractionswith the demand for them. 2. It produces alkenes, which are useful as feedstockfor the petrochemicalindustry. See more The supply is how much of a fraction an oil refinery produces. The demand is how much of a fraction customers want to buy. Very often, fractional … See more Alkanes and alkenes both form homologous series of hydrocarbons, but: 1. alkanes are saturated, their carbon atoms are only joined by C-C single bonds 2. alkenes are unsaturated, they contain at least one C=C … See more
