How does the chain length of Hydrocarbons change their properties?
As the chain length of hydrocarbons increases, their boiling point and viscosity also tend to increase. Longer chain hydrocarbons are usually less volatile and have higher boiling points compared to shorter chain hydrocarbons. Additionally, longer chain hydrocarbons are typically more viscous and have higher melting points.
How does the volatility of a hydrocarbon change as its carbon chain length increases?
As the carbon chain length of a hydrocarbon increases, its volatility generally decreases. This is because longer carbon chains have stronger intermolecular forces, such as van der Waals forces, which make it harder for the molecules to escape into the gas phase. Shorter chain hydrocarbons are typically more volatile and have lower boiling points compared to longer chain hydrocarbons.
Does the electronegativity of a carbon atom change as its p-character increases?
Yes, the electronegativity of a carbon atom generally increases as its p-character increases.
Is flammability of a substance a chemical or physical change?
Flammability is a chemical property not a change; burning is a chemical change.
How does adding a double or trible bond change the shape of the carbon backbone in a hydrocarbon?
you have dr.whelan huh
Is combustion a chemcial change?
Combustion clearly is a chemical change. In the combustion of a hydrocarbon, for example, you begin with the hydrocarbon and after combustion you end up with carbon dioxide (CO2) and water (H2O). This demonstrates that a chemical change has taken place.
Is flammability of a blanket a chemical change or chemical property?
Flammability is a chemical property; burning is a change.
Is flammability is physical reaction?
Burning is a chemical change, flammability is a chemical property.
Why is melting the property of the wax but flammability is a chemical property?
The answer is simple: flammability involve a chemical change.
Is flammability a physical properity?
Flammability is a chemical property because the matter undergoes a chemical change (change in the make-up molecules) when it is burned.
What is a chemical change in a candle?
Most candles are made from a hydrocarbon called parafin; it burns, producing carbon dioxide and water vapor.
How does the boiling point of a hydrocarbon change as its carbon chain length increases?
Generally speaking, boiling points increase as carbon chain length increases. This is because there are more atoms present in the hydrocarbon molecule and therefore more intermolecular forces (eg Van der Waals') that must be overcome. In addition the now heavier molecule requires greater energy (heat) to make the phase change to a gas. However, branching decreases boiling point; branched hydrocarbons cannot pack together as closely as unbranched ones, and so intermolecular forces are less strong. So, for example, the bp is higher for butane than 2-methylpropane (even though they contain the same number of C and H atoms).
