ALDEHYDE AND KETONE

What is the different of structural formula between aldehydes and ketones?

• In aldehyde, hydrogen is attach to carbon at carbonyl functional grouo

• In ketone, carbonyl functional group is in between the carbon atom

• In ketone, hydogen is attach to carbon at carbonyl functional group

• In aldehyde, carbonyl functional group is in between the carbon atom

Why aldehyde is more reactive than ketone?

• Aldehyde has two groups of electron donating group attach to it

• Aldehyde is less sterically hindered than ketone

• Aldehyde is more sterically hindered than aldehyde

• Aldehyde has one group of electron donating group attach to it

Are they soluble in water (for low molecular weight)?. Explain.

• No, because they are polar compound

• Yes, because they are polar compound

Why they have higher boiling points compared to ether and hydrocarbon?

• The intermolecular forces between the molecules are hydrogen bonds

• The intermolecular forces between their molecules are dipole-dipole interactions

• The intermolecular forces between the molecules are covalent bonds
