| Question | Answer |
|---|---|
| naming alcohol | C attached to OH should have lowest number, suffix "ol" |
| bp and mp are ______ than norm hydrocarbons | Higher |
| strong acid _____ ka but ______pkas | high, small |
| _______ substitutes increase acidity on phenol | electron withdrawing |
| Water + alkene | H add to least sub C and OH to more sub C |
| CH3MgBr + aldehyde | =O turns to OH and CH3 added to the C which had the carbonyl |
| oxidize prim alcol is ______ | aldehyde |
| oxidize sec alco is | ketone |
| LAH ( LiAlH) + carboxylic acid R-C=O \OH | removes the carbonyl to form alcohol |
| NaBH4 + aldehydes | adds H to C=O to form C-OH |
| alcohol + H2SO4 + heat | minor(= less sub C) and major alkene ( = more sub C)--> E1 |
| when can alcohol undergo substitution | 1.Protonated 2.converted to Tosylate 3.Form ester |
| Bulky alchol + HBr | SN1- substitutes OH with Br |
| Alcohol + SOCl2 | forms alkyl chloride |
| primary alcohol + PCC | c-OH to C=O |
| sec alcohol + Na2Cr2O7 | C-OH to C=O |
| primary alcohol + CrO3 | C-OH to C=O \OH |
| phenols + Na2Cr2O7 | OH to =O and the double bonds rearranged in the ring |
| gen formula for ether | ROR |
| naming ethers | prefix- smaller chain, suffix- larger chain "alkoxy " "alkane" |
| Williamso ether synthesis | metal alkoxides + primary alkyl halides/ tosylates |
| alkoxides attack only _____ halides | non hindered |
| ____ + mcpba = oxirane | alkene |
| Ether + O2 | ROOR (peroxides) |
| non hindered ether + Hbr | alkyly halide + alcohol (Sn2) |
| bulky ether + Hbr | alkyl halide, (Sn1) |
| epoxide + HBr | most subst C gets Br/ halide |
| epoxide + Base (Br-) | least subst C gets halide |
| grignard (chrMgBr) reacts with alcohols only in | acidid conditions |
| HBr + _______ alcohols form low yield substitution but high yield alkene | secondary and tertiary alcohols |
| KMno4 will not react with ___ alcohol | tertiary |
