Explanation:
from
de Broglie wavelength= h/ mv
substitute the values
joules= mass(kg) × acceleration (m/s^2) × distance(m)= kgm^2/s^2.
sorry I don't have my calc with me
<h3><u>Answer;</u></h3>
Both aldehydes and ketones can hydrogen bond with water molecules. ethanal has a higher BP than ethane ketones are polar molecules
<h3><u>Explanation;</u></h3>
- An aldehyde differs from a ketone by having a hydrogen atom attached to the carbonyl group, which makes aldehydes very easy to oxidise.
- Ketones lack hydrogen atom and are resistant to oxidation and are only oxidised by powerful oxidising agents which have the ability to break carbon-carbon bonds.
- <em><u>Both aldehydes and ketones are polar molecules because of the presence of the carbon-oxygen double bond, which means they can form hydrogen bonds with water molecules</u></em>.
