Alkyl halides do one of two things when they react with a nucleophile/base, such as a hydroxide ion... - correct answer (1) undergo SUBSTITUTION of the X group by the nucleophile OR (2) undergo ELIMINATION of HX to yield an alkene carbon-halogen bonds in alkyl halides are polar and the carbon atoms are electron-poor, thus, alkyl halides are ELECTROPHILES Nucleophilic Substitution Reactions - correct answer -each st...

Unit 6: Principles and Applications of Chemistry II Delivery guidance Scientists and laboratory technicians must be able to use and apply key science concepts to work efficiently and effectively in science and science-related organisations. This unit builds on and extends the key science concepts covered in Unit 2: Principles and Applications of Chemistry I. A strong grasp of these concepts will enable learners to use and apply their knowledge and understanding in vocational contexts...
