Question

determine which of the following is true. select all that apply. Both aldehydes and ketones contain carbonyl groups: In aldehydes, the carbonyl carbon atom is bonded to a hydrogen atom, whereas in ketones the carbonyl carbon atom. Determine which of the following statements are true. Select (check) the correct statements. Propanal is a gas at room temperature, whereas formaldehyde (methanal) is a liquid at room temperature. Both dehydes and ketones can hydrogen bond with water molecules. Aldehydes contain a carbon-oxygen double bond. Ketones with fewer than five carbon atoms are soluble in organic solvents, but not in water Butanal has a higher boiling point than 2-butanol. Ketones have lower boiling pants than alcohols of similar size.

Explanation / Answer

1) False, these are aldehydes, have higher boiling points than room temperature, therefore propanal will be liquid

2) True, since they both contain C=O group, can bond with H-O-H (hydrogen) from water

3) True, since H-C=O is the functional group of aldehydes

4) FALSE, they will be soluble in water as well

5) FALSE, alcohols have higher boiling points than aldehydes

6) TRUE, in general, alcohosl hav ehigher BP
