Select the longest continuous carbon chain, containing the hydroxyl group, and derive the parent name by replacing the -e ending with -ol. 2. Number the carbon chain, beginning at the end nearest to the hydroxyl group. 3. Number the substituents and write the name, listing substituents alphabetically. Some Examples:
<2-13-ccloheranediol HO 4 4dimethyicycloheranol Alcohols are also known by a wide variety of common names, some of which are given below: H3C Isopropy alcohol NButyl alcohol c-methyl-2-propanon (123-propanetniol CH2OH Allylalcohol Benzyl alcohol Simple ethers are named either by identifying the two organic residues and adding the word ether, or, if other functionality is present, the ether residue is named as an alkoxy substituent, as shown below ethyl methyl ether 4-bromo-l-methoxybu Some example:
Alcohols are also known by a wide variety of common names, some of which are given below: Simple ethers are named either by identifying the two organic residues and adding the word ether, or, if other functionality is present, the ether residue is named as an alkoxy substituent, as shown below: Some Examples:
e-methyl-1-proporypropane chloro 1(2-chloroproporyh2-methyipropane Reactions of alcohols Conversion to Alkyl Chlorides by Reaction with HCl: Tertiary alcohols, or alcohols which can lose the hydroxyl group to form a stable carbocation, can undergo an S,I substitution reaction with hcl gas dissolved in ether to give the corresponding alkyl chloride. Again, the reaction is limited to alcohols that can from stable carbocations ether.0°c CH Conversion to Alkyl Bromides by Reaction with PBr. Primary and secondary alcohols react with PBr, to form an intermediate phosphite ester which undergoes S,2 attack by bromide anion to yield the alkyl bromide with inversion of configuration(the stereochemical inversion is simply a result of the displacement)
Reactions of Alcohols Conversion to Alkyl Chlorides by Reaction with HCl: Tertiary alcohols, or alcohols which can lose the hydroxyl group to form a stable carbocation, can undergo an SN1 substitution reaction with HCl gas dissolved in ether to give the corresponding alkyl chloride. Again, the reaction is limited to alcohols that can from stable carbocations. Conversion to Alkyl Bromides by Reaction with PBr3: Primary and secondary alcohols react with PBr3 to form an intermediate phosphite ester which undergoes SN2 attack by bromide anion to yield the alkyl bromide with inversion of configuration (the stereochemical inversion is simply a result of the SN2 displacement)
R ether.35°c PB -Br Displac B CH3CH CH3CH2 a phosphite ester Conversion to Alkyl Chlorides by Reaction with SoCl, Primary and secondary alcohols react with SoCl, in polar solvents (i. e, pyridine) to form an intermediate sulfite ester which undergoes S2 attack by chloride anion to yield the alkyl chloride with inversion of configuration(the stereochemical inversion is simply a result of the S,2 displacement). If the reaction is performed in a non-polar solvent such as benzene, an unusual S, i mechanism occurs involving frontside attack, and yielding retention of stereochemistry. This reaction is unusual, but is often useful if you desire to control the stereochemical course of a synthesis sOCI2 pendine Non-Polar CI/NN2Displacement SNi Displacement with Inversion with Retention a sulfite ester a sulfite este Dehydration of Tertiary Alcohols: Tertiary alcohols, or alcohols which can lose the hydroxyl group to form a stable carbocation, can undergo an acid-catalyzed El elimination reaction to form the corresponding alkene. Again, the reaction is limited to alcohols that can from stable carbocations
Conversion to Alkyl Chlorides by Reaction with SOCl2: Primary and secondary alcohols react with SOCl2 in polar solvents (i.e., pyridine) to form an intermediate sulfite ester which undergoes SN2 attack by chloride anion to yield the alkyl chloride with inversion of configuration (the stereochemical inversion is simply a result of the SN2 displacement). If the reaction is performed in a non-polar solvent such as benzene, an unusual SNi mechanism occurs involving frontside attack, and yielding retention of stereochemistry. This reaction is unusual, but is often useful if you desire to control the stereochemical course of a synthesis. Dehydration of Tertiary Alcohols: Tertiary alcohols, or alcohols which can lose the hydroxyl group to form a stable carbocation, can undergo an acid-catalyzed E1 elimination reaction to form the corresponding alkene. Again, the reaction is limited to alcohols that can from stable carbocations
