OCR A Level Chemistry Exam Questions With 100% Correct Answers Acid - answerA species that is a proton donor. activation energy - answerThe minimum amount of kinetic energy that particles need to have in order to react when they collide addition polymer - answerA very long molecular chain formed by repeated addition reactions of many unsaturated alkene molecules (monomers). addition polymerisation - answerThe process in which unsaturated alkene molecules (monomers) add on to a growing po...

MCAT Organic Chemistry Exam Questions and Answers Instantaneous Dipole Moment - Answer-Exists in an otherwise nonpolar molecule. Occurs because the electrons in a bond move about the orbital and at any moment may not be distributed exactly between the two bonding atoms, even when the atoms are identical. London Dispersion Forces - Answer-Occur between two instantaneous dipoles; the weakest dipole-dipole force (vs. hydrogen bonds which are the strongest dipole-dipole forces). Wolff-Kishner...
