Homework Answers
1) 3-methylbutan-1-ol undergo oxidation with PDC reagent to form 3-methylbutanal as major product. Overoxidation to acid with this reagent is not possible with this mild oxidizing reagent.
2) Cyclopentanone is reduced with sodium borohydride to form cyclopentanone
3) Ketone group of 1-phenylbutan-1-one is protected with ethanol to form (1,1-diethoxybutyl)benzene as major product.
4) octan-4-one react with diethyl amine to form imine (Z)-N,N-diethyloct-3-en-4-amine with cis and trans compound
5) 2-hydroxybenzaldehyde reacts with Grignard reagent to form 2-(1-hydroxy-3-methylbutyl)phenol as major product. Here excess of Grignard is needed as 1 mole of Grignard will be quenched by acidic phenolic proton.
6) 2,3-dimethylpent-1-ene react with cobalt catalyst in presence of CO and H2 to form 3,4-dimethylhexanal as major product.
