|---|---|---|---|---|---|
| What is the characteristic that distinguish alkenes from alkanes when ranking boiling point and melting point? | show 🗑
|
||||
| show | Elimination of alcohols and alkyl halides. i.e-dehydration and dehydrohalogenation (hydrogen and a halide)
🗑
|
||||
| show | E1 and E2
🗑
|
||||
| What is the E1 reaction? | show 🗑
|
||||
| What distingushes E1 from SN1? | show 🗑
|
||||
| What is the E2 reaction? | show 🗑
|
||||
| What are the features that distinguish E2 from SN2? | show 🗑
|
||||
| What are the reactions that an alkene undergo? | show 🗑
|
||||
| What is the alkene reduction? | show 🗑
|
||||
| What is electrophilic addition of alkenes? | show 🗑
|
||||
| What is the Markovnikov rule? | show 🗑
|
||||
| show | The "X" of the HX goes to the most stable carbocation intermediate while the "H" goes to the least substituted carbon forming an alkyl halide. The alkene reaction with dihalide initially forms a cyclic halonium ion followed by a dihalo compound.
🗑
|
||||
| show | Adding water in presence of an acid (sulfuric acid) yields an alcohol
🗑
|
||||
| show | When a bromine radical is added to an alkene, it adds to the least substituted carbon (anti-markovnikov). It occurs in presence of peroxides and UV light.
🗑
|
||||
| What is the hydroboration of alkenes? | show 🗑
|
||||
| show | An alkene reacts with cold KMNO4 and results in a 1,2 vicinal diols (on the same side). When reacted with hot KMNO4, nonterminal alkene result in two moles of carboxylic acids. But, if the nonterminal alkenes are disubstituted, a ketone is formed.
🗑
|
||||
| show | A terminal alkene reacts with hot KMNO4, and results in a carboxylic acid and carbon dioxide. If terminal alkene is disubstituted, then a ketone and a carbon dioxide is formed.
🗑
|
||||
| Explain the ozonolysis of an alkene? | show 🗑
|
||||
| show | A primary alcohol for an aldehyde and a secondary alcohol for a ketone.
🗑
|
||||
| Explain the reaction of a peroxycarboxylic acid (-COOOH) with an alkene? | show 🗑
|
||||
| Explain the polymerization of alkenes? | show 🗑
