Which test says what

You will finish three small functions that give the result of a test for an amine of a given class. The class is "primary", "secondary" or "tertiary". For nitrous acid, a flag says whether the nitrogen is on a ring.

The idea. The carbylamine test is positive only for primary amines. Hinsberg's test gives a soluble product for a primary amine, an insoluble one for a secondary amine and none for a tertiary amine. Nitrous acid gives nitrogen gas only with a primary amine whose nitrogen is not on a ring.

Your tasks.

1. Complete carbylamine(kind) so that it returns True for a positive test.
2. Complete hinsberg(kind) so that it returns "soluble", "insoluble" or "none".
3. Complete gives_gas(kind, ring) so that it returns True when nitrous acid gives nitrogen gas.
