Ch4: Alcohols and Alkyl Halides

Summary Alcohols (R-OH) and alkyl halides R-X (X = F Cl Br or I) are important functional groups as they are fundamental building blocks (starting materials reagents) for the synthesis of more complex organic materials Alkyl halides can be prepared via substitution reactions: Radical halogentaion of alkanes R-H + X 2 R-X + HX

How does the inductive effect explain the reactivity of

$begingroup$ 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 easily than in
