Properties and Behavior of Hexane

The video explores the intermolecular forces in hexane (C6H14). It begins by examining the absence of ions due to the covalent bonds between carbon and hydrogen, both non-metals. The video then discusses the non-polar nature of hexane, highlighting its symmetrical molecular structure and similar electronegativities of carbon and hydrogen. The primary intermolecular force in hexane is identified as London dispersion forces, which increase with the length of the molecule, affecting the boiling point. The video concludes by comparing hexane's liquid state at room temperature to the gaseous state of shorter hydrocarbons like ethane and methane.

What type of bonds are present in hexane?

• Ionic bonds

• Because it is a non-metal

• Because it is a gas

What is the polarity of hexane?

• Polar

• Amphipathic

• Ionic

• Nonpolar

What is the main intermolecular force in hexane?

• Dipole-dipole interactions

• Ionic interactions

• London dispersion forces

• Hydrogen bonding

Why does hexane have nonpolar bonds?

• Because of its ionic nature

• Because it is a metal

• Due to similar electronegativities of carbon and hydrogen

• Due to its high boiling point

How does the length of a hydrocarbon affect its boiling point?

• Longer hydrocarbons have lower boiling points

• Length does not affect boiling point

• Longer hydrocarbons have higher boiling points

• Shorter hydrocarbons have higher boiling points

What state is hexane at room temperature?

• Gas

• Plasma

• Solid

Which of the following hydrocarbons is a gas at room temperature?

• Hexane

• Ethane

• Methane

• Both Ethane and Methane

What happens to the boiling point as more carbons are added to a hydrocarbon?

• It decreases

• It remains the same

• It increases

• It fluctuates
