WebPolyesters and polyamides are types of synthetic polymer. Which statements are correct? 1 They are made by addition polymerisation. 2 They are made by condensation polymerisation. 3 The monomers from which they are made are unsaturated hydrocarbons. 4 The monomers from which they are made contain reactive functional groups at their ends. Web1 dag geleden · In an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. The other pair is more loosely held in an orbital above and below the plane of the molecule known as a pi bond. nbc30.com weather
