Cyclohexanone forms cyanohydrin in a good yield, but 2,2,6-trimethylcyclohexanone does not. It is due to:

1. Low electrophilicity in 2,2,6-trimethylcyclohexanone

2. Less steric crowd in  2,2,6-trimethylcyclohexanone

3. More steric crowd in  2,2,6-trimethylcyclohexanone

4. High electrophilicity in 2,2,6-trimethylcyclohexanone

There is only one –NH₂ group involved in semicarbazone formation out of two –NH₂ group. It is due to:

1. Resonance  of one type of –NH₂ group

2. Inductive effect of one type of –NH₂ group

3. Hyperconjugation of one type of –NH₂ group

4. Reverse hyperconjugation of one type of -NH₂ group
