* Ethene is used in the production of ethylene glycol (1,2-ethanediol) which is used as an automotive antifreeze agent and as a precursor to polymers. Find my revision workbooks here: https://www.freesciencelessons.co.uk/workbooksIn this video, we look at addition polymerisation. In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. Ethane is used in the production of ethylene for making plastics, anti-freeze and detergents; it's a ripening agent for foods, a refrigerant, a substance in producing welding gas and a primary ingredient in mustard gas. Ethanoic acid, also called acetic acid, is a weak carboxylic acid with the formula C2H4O2 or CH3COOH. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. Industrial uses of ethene 1. Details of this assay are included in the resource. Properties of Ethene (ethylene) colourless gas at room temperature and pressure â Melting point = -169°C â Boiling point = -104°C . Ethene is used to prepare lots of different things. So if ethanol undergoes the dehydration reaction, the corresponding alkene produced will be ethene. 1.a.A Monomer is a molecule that may bind chemically to other â¦ 2020. Produced by Science & Plants for Schools (SAPS), this investigation looks at the effects of ethene of fruit ripening. Ethene is a colourless gas and is produced by plants, acting as a plant growth substance. Its presence can be detected using a simple bioassay using germinating seedlings. The carbon atom doesn't have enough unpaired electrons to form the required number of bonds, so it needs to promote one of the 2s 2 pair into the empty 2p z orbital. Electrophilic addition: Ethene with Bromine Ethanol From Ethene - Alcohols - GCSE Chemistry (Single Science) Revision - Other - BBC Bitesize . This page contains the AQA GCSE Chemistry Polymers Questions and kerboodle answers for revision and understanding Polymers .This page also contains the link to the notes and video for the revision of this topic.. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a $$\pi$$ bond. Ethanoic acid uses include food additives, other chemicals, medicine and plastics production. C 11.1 Addition polymerisation AQA GCSE Chemistry Chapter C11 Polymers Kerboodle Answers Page No 169. Ethene is used to accelerate the ripening of fruits and is most commonly used on bananas and also on citrus fruits. Industrial Uses of Ethene
