Frequently asked questions
- What organic mechanisms are tested in H2 Chemistry?
- Nucleophilic substitution (SN1/SN2), electrophilic addition, nucleophilic addition (carbonyls), esterification, and elimination. Always show curly arrows from electron pairs to electrophilic centres.
- How do I distinguish structural and stereoisomerism?
- Structural isomers have different connectivity. Stereoisomers have the same connectivity but different spatial arrangement — e.g. cis-trans (geometric) and optical (enantiomers).
- What are common H2 organic chemistry mistakes?
- Wrong curly arrow direction, incomplete mechanisms, and confusing aldehydes with ketones in test-tube reactions. Practise drawing full mechanisms with all intermediates.
