The flammability DECREASES as the chain length increases. Methane (C1) is natural gas and by definition very flammable. C20 is basically paraffin wax and it will burn but with much greater difficulty.
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.
Yes, the electronegativity of a carbon atom generally increases as its p-character increases.
you have dr.whelan huh
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.
Flammability is a chemical property not a change; burning is a chemical change.
Flammability is a chemical property; burning is a change.
Burning is a chemical change, flammability is a chemical property.
As the number of carbon atoms in a hydrocarbon increases, the state of the hydrocarbon typically transitions from gas to liquid to solid. Smaller hydrocarbons, such as methane and ethane, are gases at room temperature, while medium-sized hydrocarbons, like hexane and octane, are liquids. Larger hydrocarbons, such as those found in heavy oils and waxes, tend to be solid at room temperature due to increased molecular weight and stronger intermolecular forces. This trend is influenced by factors such as molecular structure and the presence of functional groups.
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).
The answer is simple: flammability involve a chemical change.
Most candles are made from a hydrocarbon called parafin; it burns, producing carbon dioxide and water vapor.
