Conformers
Just to clear it for once and for all
- When is torsional strain the least?
- When is steric strain the least?
- When is angle strain the least?
Also are there any other types of strains I'm missing?

Factors affecting acidity
Does -I group increase acidity or decrease it?
My thinking is that +I increases acidity and -I decreases acidity as +I groups increases electron density so the carbocation formed will be more stable as it will be balanced by the electron density.

Are all optically active compounds chiral?
or are all chiral compounds optically active?
Are stereoisomers the same as optically isomers?
