    is my equation correct ? or there's no reaction for the alkyl hallide and the KCN in the picture?

    I'd say that the phenyl group would prevent this reaction from occurring. The carbon would not be sufficiently polarised to be attacked by the CN- nucleophile. The phenyl group would delocalise the positive charge produced by the more electronegative chlorine pulling electron density away from the carbon.

    The one phenyl doesn't actually pose that much of a barrier - sterics isn't much of an issue for SN2 and pi donation actually stabilises the transition state. Solvent isn't ideal but cyanide is a good nucleophile so it's pretty reasonable to say a reaction would occur.

    Actually after checking Clayden yeah you're right

    so the reaction above is feasible?
