Draw the curved arrow mechanism for the addition of HCN in water with NaOH to 3-methylcyclopentan-1-one to give the corresponding cyanohydrin in the fewest steps. Draw the arrows that lead to the resonance structures with full octets around each atom other than hydrogen. Draw all electrons and charges if necessary on all structures; do not show any inorganic side products or counterions. Reagents needed for each step are provided in the boxes.

Reaction mechanism consists of three steps which are depicted below.

Explanation:

In the first step, NaOH reacts with HCN to produce stronger nucleophile .In the second step, gives nucleophilic addition reaction at the carbonyl center of 3-methylcyclopentan-1-one.In the third step, alkoxy ion removes a proton from molecule to form cyanohydrin.Full mechanistic pathway has been shown below.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
