Answer 2

-The C in the C=O becomes polarised
-The Pi bond electrons are unavailable due to polarisation

Answer 4

nucleophilic addition

Question 5

Draw the mechanism for nucleophilic addition for aldehyde?

Answer 5

-Arrow starting from H- ion that has both electrons to the carbon molecule that is bonded to O atom
- Dipoles on Carbon and Oxygen, and arrow from double bond to oxygen
-molecule that has oxygen has arrow starting from ion on O and goes to external h20 molecule
-Dipoles on water drawn
- Final molecule made and OH- made
