Question | Answer |
Hydrocarbons, as the name implies, are compounds whose molecules contain: | Carbon and Hydrogen |
Carbon characteristic of alkanes | Carbon-carbon bonds are singular |
Hydrocarbons with carbon-carbon double bond | Alkenes |
Hydrocarbons with carbon-carbon triple bond | Alkynes |
Def. of cycloalkanes | Alkanes in which all or some of the carbon atoms are arranged in a ring |
A cycloalkane containing a single ring have ____ _____ hydrogen atoms than regular alkanes | Two fewer |
This alkane makes up 80% of our natural gas | Methane |
What is the bond angle of ALL alkanes? | 109.5 degrees |
What is the geometry of ALL alkanes? | Tetrahedral |
Hybridization of ALL alkanes? | sp3 |
Are alkanes saturated or unsaturated compounds? and why? | Saturated, because they are single bonds. They contain the most hydrogens thatthey are able to possess. |
What alkane makes up 20% of our natural gas? | Ethane |
Name for alkane that can have different structures while having the same formula: | constitutional isomers |
Alkane (minus) Hydrogen = | Alkyl (change -ane to -yl) |
Four halogens found in alkylhalides: | F- fluoro; Cl- chloro; Br- bromo; I- iodo |
Hydrocarbons have high or low melting and boiling points? | Low (Van der Waals forces) |
Alkylhalides - MP and BP compared to hydrocarbons? | Slightly higher |
Solubility of hydrocarbons | Not soluble in H20 |
Solubility of alkylhalides | Slightly soluble in H20 |
Name of hydrocarbon involved in communication | Communication |
Name of hydrocarbon described as a "sex attractant". | Undecane |
The ONLY drinkable alcohol: | I: Ethanol (C: Ethyl alcohol) |
T/F - Alcohol is an alkane. | False |
Wood alcohol is what type of alcohol? | Methanol |
What makes up denatured alcohol? | Ethanol mixed with methanol |
Uses for methanol: | Fuel for high-performance cars and race cars |
How does methanol burn? | Intense yet unnoticeable light blue flame |
Alternative name for methanol: | Wood alcohol |
Alpha carbons are connected to ____ | OH |
Beta carbons are attached to ___ | Alpha carbon |
Primary (1º) atom characteristic: | One beta carbon connected to alpha carbon |
Secondary (2º) atom characteristic: | Two beta carbons connected to alpha carbon |
Tertiary (3º) atom characteristic: | Three beta carbons connected to alpha carbon |
Stereoisomers - characteristic | Same structures, different arrangement in space. trans/cist |
Trans = | Across |
Cist = | Boat-shaped |
Cist & trans are meant for all ______ | Non-1-alkenes |
Solubility of alcohol | Soluble in H2O up to 6 carbons |
Properties of alcohol | High MP & BP (hydrogen bonds) |
What type of alkane is most stable hydrocarbon? | Cycloalkanes |
The most stable cycloalkane: | Cyclohexane |
Most stable sawhorse structure | Chair configuration |
Least stable sawhorse structure | Boat configuration |
All cycloalkanes want what angle? | 109.5º |
Cyclopropane gets what BA? | 60º |
Cyclobutane gets what BA? | 90º |
Cyclopentane gets what BA? | 108º |
How do you calculate Angle Strain? | Ideal angle (109.5º) - Actual Angle = Angle Strain |
When the actual angle goes beyond 360º, you add ______ for each side. | 180º |
When the number of sides is higher than 6, the angle _______ __ ______ and hydrogens overlap, getting in the way. | Remain at 109.5º |
What results from a cycloalkane containing more than 6 sides? | Stearic hindrance |
Hydrogenation - hydrogenated = | Trans fats |
