Preparation of Phenols and Ethers - Williamson and Other Methods

Which alcohol is produced by the hydroboration-oxidation of 1-pentene?

1-Pentene (CH₂=CH-CH₂CH₂CH₃) undergoes hydroboration-oxidation with BH₃ and H₂O₂, adding -OH anti-Markovnikov to form pentan-1-ol (CH₃(CH₂)3CH₂OH).

Preparation of Alcohols - from Alkenes Haloalkanes Carbonyls Grignard

Which alcohol is produced when ethyl magnesium bromide reacts with ethanal followed by hydrolysis?

Ethyl magnesium bromide (CH₃CH₂MgBr) reacts with ethanal (CH₃CHO), adding the ethyl group to the carbonyl, yielding butan-2-ol (CH₃CH(OH)CH₂CH₃) after hydrolysis.

Physical Properties and Acidity of Alcohols and Phenols

Which alcohol is produced when ethyl magnesium bromide reacts with propanal followed by hydrolysis?

Ethyl magnesium bromide (CH₃CH₂MgBr) reacts with propanal (CH₃CH₂CHO), adding the ethyl group to the carbonyl, yielding pentan-3-ol (CH₃CH₂CH(OH)CH₂CH₃) after hydrolysis.

Chemical Reactions of Alcohols - Dehydration Oxidation Esterification

Which alcohol is produced when 1-butene reacts with BH₃ followed by H₂O₂ and OH-?

1-Butene (CH₂=CHCH₂CH₃) undergoes hydroboration-oxidation, adding -OH anti-Markovnikov to form butan-1-ol (CH₃CH₂CH₂CH₂OH).
