Challenges in Using the Wittig Reaction and Alternative Olefination Methods
Why Can’t I Just Use a Wittig Reaction Here? The Wittig reaction is a powerful tool in organic synthesis, but it is not always the best choice in every situation....
Is Organic Chemistry as a Second Language Enough for Self-Learning Without Additional Textbooks?
Is Organic Chemistry as a Second Language (OCASL) Enough to Self-Learn Organic Chemistry? Organic Chemistry as a Second Language (OCASL) alone is not sufficient to fully self-learn organic chemistry; it...
What Does “80% Selectivity” Mean in Chemistry? Understanding Its Role in Stereoselectivity and Polymer Chemistry
Understanding “80% Selectivity” in Chemistry “80% selectivity” refers to the preference of a chemical reaction to produce one product over another at an 80% proportion. It typically means that the...
Are (3R,4S)-3,4-Dimethylhexane and (3S,4R)-3,4-Dimethylhexane Identical Based on Counting Direction?
Are (3R,4S)-3,4-Dimethylhexane and (3S,4R)-3,4-Dimethylhexane the Same? Yes, (3R,4S)-3,4-dimethylhexane and (3S,4R)-3,4-dimethylhexane represent the same molecule due to its meso nature, meaning the stereochemical descriptors change with the direction of numbering but...
Why Benzoic Acid Fails to Qualify as a Strong Acid: Key Factors Explained
Why Benzoic Acid Is Not a Strong Acid Benzoic acid is not a strong acid because it does not fully dissociate in water and its conjugate base lacks extensive resonance...

Easy and Cheap Preparative TLC with Regular TLC Plates Preparative thin-layer chromatography (prep TLC) can be performed effectively using regular TLC plates made from inexpensive materials. This approach allows for...
Identifying the Blue-ish Component Above Xanthophyll in a TLC Plate of Spinach
TLC Plate of Spinach: Identifying the Blue-ish Component Above Xanthophyll The blue-ish component on the right spot above the xanthophyll on a Thin Layer Chromatography (TLC) plate of spinach is...
Why Does bromine Yield Fewer Products than Chlorine in Reactions with Light?
Why Does Br2/hv Yield Fewer Products than Cl2/hv? Bromination (Br2/hv) produces fewer products than chlorination (Cl2/hv) because bromination is highly selective, favoring reaction at tertiary carbons, while chlorination is less...
Understanding Meso Compounds and Their Molecular Symmetry
Is This a Meso Compound? A meso compound contains chiral centers but is overall achiral due to an internal plane of symmetry. This symmetry cancels out optical activity. Identifying whether...
How to Get Proper Fischer Projections: A Step-by-Step Guide to Accurate Molecular Representation
How to Get Proper Fischer Projections To get proper Fischer projections, position the longest carbon chain vertically with the most oxidized carbon at the top. Place alkyl groups at the...
