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
