Web3 de abr. de 2024 · We know that alcohols react with active metals e.g. Na, K, etc. to give corresponding alkoxides. Alcohols contain hydrogen attached to oxygen. Compounds containing hydrogen attached more electronegative elements such as oxygen are acidic. Alcohols are acids but their acidic strength is very less. WebAlkynes are converted into alcohols and amines through a formic acid-participated alkyne-to-ketone transformation and transfer hydrogenation process. The reaction proceeds well under aqueous conditions, furnishing chiral alcohols directly from alkynes for the first time.

Web$\begingroup$ @G M.I haven't yet understood, how the presence of more no of carbon atoms in tertiary alcohols, make them more reactive than primary. What I thought was, if tertiary is more reactive than primary alcohol, it means that carbon oxygen bond is weaker in tertiary alcohol than in primary, which is making the -OH bond in tertiary alcohol to break … WebIsocyanates react with alcohols and phenols to form urethanes. In general, rates of urethane formation decrease in the following order primary alcohols > secondary alcohols > 2-alkoxyethanols > l-alkoxy-2-propanols. Isocyanates can react with urethanes to form allophanates. This reaction is much slower than the reaction of isocyanate with alcohol.
