Aldehydes and Ketones
Definition: An aldehyde is an organic compound containing a C=O group
at the end
of a hydrocarbon chain.
Written as R-CHO
Following are examples of Aldehydes
Hint:C=O group must at the end of a hydrocarbon chain.
We don't need to name it, so following is easy explain about that.
like this example.It called methanal.
1、Find the parent chain.(This example is methane.)
2、Then change "e" to "al",so the name of this example is methanal.
For another example.
1、find the parent chain.(pentane)
2、branch point is on second carbon,so we need add 2 at front
3、CH3 only have one carbon, so we should add "methyl"
4、This is aldehyde, so we need change pentane to pentanal
so the name of this aldehyde is
A ketone is an organic is an organic compound containing a C=O group at
a position OTHER THAN AT THE END OF
A HYDROCARBON CHAIN.
WRITTEN AS R-CO-R
Hint:C=O group must at a position other than at the end of a hydrocarbon chain
We don't need to name it,so following is easy explain about it.
The way of ketones' naming is same as aldehydes.
but aldehydes is change end of name to "al",and ketone is change to "one"
1 same as aldehydes ,we should find parent chain first.(propane)
2 change the "e"to "one"
3 so this ketones named propanone
