Draw and name the missing reactant(s) or products in each reaction and identify the type of reactions. [C-12]
a) 3-ethyl-4,4-dimethyl-2-pentanol + [O] → 3-ethyl-4,4-dimethyl-2-pentanone + water (oxidation reaction)
b) CH3CH2COCH3 + H2 →CH3CH2CH(OH) CH3 (hydrogenation reaction)
c) CH3CH2CH2CHO + [O] → CH3CH2CH2COOH (oxidation reaction)
d) HC≡CH + HBr → CH2?CHBr (addition reaction)
Step-by-step explanation
Draw and name the missing reactant(s) or products in each reaction and identify the type of reactions. [C-12]
a) 3-ethyl-4,4-dimethyl-2-pentanol + [O] → 3-ethyl-4,4-dimethyl-2-pentanone + water (oxidation reaction)
When a secondary alcohol is oxidised, it is converted to a ketone.
b) CH3CH2COCH3 + H2 →CH3CH2CH(OH) CH3 (hydrogenation reaction)
Hydrogenation of ketone result in addition of hydrogen across the carbon oxygen double bond and a secondary alcohol is formed.
c) CH3CH2CH2CHO + [O] → CH3CH2CH2COOH (oxidation reaction)
When an aldehyde is oxidized the product that results is a carboxylic acid (COOH group).
d) HC≡CH + HBr → CH2?CHBr (addition reaction)
Hydrogen bromide is added across the triple bond which takes an alkyne to an alkane.
