In 1945, a woman named Beulah Hunter, who was 25 at the time, gave birth to a healthy, normal daughter named Penny Diana after the record-breaking pregnancy. According to the New Health Guide, the length of the pregnancy was verified by her menstrual cycle and the date of her positive pregnancy test.
In chemistry, a ketone (alkanone) /ËkiËtoÊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond).
You will remember that the difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. Ketones don't have that hydrogen. The presence of that hydrogen atom makes aldehydes very easy to oxidise.
