The reaction is obtained by the action of alcholic KCN and what?

Answer»

1-butyl ehtyl ether
2-methyl 1-propene
2-2-dimethyl butane
isopropyl n-propyl ether

Solution :Sodium ETHOXIDE is a strong base. The nucleophile `C_(2)H_(5)O^()` can not attack at the carbon of C-Cl due to steric hindrance. Hence, ELIMINATION reaction occursto fomr alkene.
`CH_(3)- UNDERSET(CH_(3)) underset(|)overset(CH_(3)) overset(|)C-Cl+ underset("alc")(C_()H_(5)ONa)+ CH_(3)- overset(CH_(2)) overset(||)C-CH_(3)+C_(2)H_(5)OH+NaCl`
