Alcohol in acidic potassium dichromate does what type of reaction alcohol oxidation In alcohol oxidation primary becomes `primary`, secondary becomes `secondary`, tertiary has `tertiary` primary: aldehyde secondary: carboxylic acid tertiary: no reaction Color of potassium dichromate before and after reaction (used in breathalyzer): `before`, `after` before: orange after: green What does a nucleophile have (optionally has charge) lone pair Common nucleophiles hydroxyl group amine group cyanide group What do nucleophiles substitute themselves into, having the thing that got substituted going back into original electronegative bonds Example of bond nucleophile would attack C-Cl Homolytic fission vs heterolytic fission: in heterolytic both `a` go to one molecule a: electron Opposite of oxidation of alcohol is reduction of aldehyde/ketone Reduction of aldehyde/ketone requires `thing`, which gives `ion` thing: reducing agent ion: H- What does ketone get reduced to secondary alcohol Stronger reducer: `strong`, weaker: `weak`, only strong can reduce `a` strong: LiAlH4 weak: NaBH4 a: carboxylic acid What does substitution of alkanes require UV light Three steps of substitution of alkanes: `1`, where `a` happens, `2`, where `b` happens (assuming Cl2 is reacting), `3`, where `c` happens 1: initiation a: homolytic fission 2: preparation b: H goes to the unpaired Cl 3: termination c: Cl goes to the unpaired C What is required for hydogenation (where H gets added to double/triple bonds, making them singles) nickel hydrogen gas 180 C In polymerization what pairs to the left and right C double bond What does esterification rely on le chatelier principle What is on the left of esterification alcohol carboxylic acid What is on the right of esterification ester water What are electrophiles H+ Cl+ NO2+ CH3+ Electrophiles attack `bond` because `reason` bond: C=C reason: high electron density What catalyst is needed to hydrate something with electrophilic substitution H2SO4 How many hydrogens get switched in electrophilic addition 2 What does acidified potassium dichromate need to oxidize alcohols heat `chemical` is used in `reaction` to test for alkenes, changing from `original` color to `new` color chemical: bromine reaction: electrophilic substitution original: red new: clear Polymerization reaction where you have OH on both sides or OH and NH2 and it releases H2O condensation Polymerization where a double bond becomes a single bond with 1 bond to the left and one bond to the right addition
