Why is it important to control the temperature of the reaction when adding the acids? Explain why carboxylic acids are much stronger acids than alcohols. How do halogens (Cl_2, Br_2, I_2) react with halides (Cl^-, Br^-, I^-)? Can we explain this reactivity?
What are alkaloids and why do animals in nature stay away from these organic substances? What effect do the fragments of crushed glass have on the melting point of benzoic acid, and why? Why do all naturally occurring fatty acids contain an even number of carbon atoms? Why...
This is on account of the reason that the remaining carbonions left after the abstraction of alpha-hydrogen atom by the base are resonance stabilised. For more details. consult section 8 (adol Condensation).

Explain why the strongest acids are assigned the lowest pH values. Why are carboxylic acids and phenols acidic? For each pair of acids, a state in which acid is a stronger acid, and briefly explain. H_2O and H_2S Why is it that when you have a s...
Why are carboxylic acids and phenols acidic? Why is a buffer able to resist drastic changes to pH upon the addition of an acid or a base? Explain. Why is B(OH)_3 a stronger acid than Al(OH)_3? Why do we need acid-base indicators that change at pH ...
View Solution Which isomer will have a higher boiling point? View Solution Although the H-bonding in hydrogen fluoride is much stronger than that in water, yet water has a much higher boiling point than hydrogen fluoride. Why? View Solution ...
Amino acids are the small molecule building blocks of peptides and feature, as the name implies, a basic amine functionality and a carboxylic acid functionality disposed about a chiral carbon center. Although many natural amino acids are known, only 22 are so-called proteinogenic, that is they...
Why are aqueous solutions of amines basic? Show, with equations, how the dissolution of an amine in water is similar to the dissolution of ammonia in water.Why are carboxylic acids and phenols acidic?Explain why the strongest acids are assigned the lowest pH values....
