Name the carbonyl compound
You will finish a program that names a straight-chain aldehyde or ketone from the number of carbon atoms and the place of the C=O. Three small parts are missing.
The idea. The C=O at an end of the chain makes an aldehyde, named -al. Inside the chain it makes a ketone, named -one. The number is counted from the end that gives the carbonyl carbon the smaller value.
Your tasks.
- Complete
locant(n, place)so that it returns the smaller ofplaceandn + 1 - place. - Complete
is_aldehyde(n, place)so that it is true when the C=O is on the first or the last carbon. - In
name_of, return the right ending for an aldehyde, for propanone or butanone, and for the other ketones.
