3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What are amines?Show answer
The strength of an amine base depends on how available the lone pair is. Aliphatic amines such as ethylamine are stronger bases than ammonia because the alkyl group releases electron density onto nitrogen, making the lone pair more available. Aromatic amines such as phenylamine are weaker than ammonia because the lone pair is partly delocalised into the benzene ring and so is less available to bond a proton.

What is q2?Show answer
State one reason addition polymers are difficult to dispose of compared with condensation polymers. [2 marks]
