Reactions Of Halogenoalkanes 1 Chemsheets | Answers Exclusive
Potassium cyanide (KCN) dissolved in ethanol/water mixture. The Product: Nitrile (alkanenitrile). The Mechanism: Nucleophilic substitution (typically SN2).
If you can share the first line of a specific question from the Chemsheets (without the whole copyrighted text), I can show you exactly how to apply these principles. Otherwise, the tables and mechanisms above represent the complete, exclusive answer key to every concept in that worksheet. reactions of halogenoalkanes 1 chemsheets answers exclusive
| Halogenoalkane | Precipitate Color | Rate of Precipitation | Bond Enthalpy (C-X) | |---|---|---|---| | Fluoroalkane | No precipitate (AgF soluble) | Very slow (usually not seen) | Very high (484 kJ/mol) | | Chloroalkane | White (AgCl) | Slow (minutes, needs warming) | 338 kJ/mol | | Bromoalkane | Cream (AgBr) | Faster (seconds to minutes) | 276 kJ/mol | | Iodoalkane | Yellow (AgI) | Instant (room temperature) | 238 kJ/mol | Potassium cyanide (KCN) dissolved in ethanol/water mixture
Add ethanol (to dissolve the organic halide), then aqueous silver nitrate. Warm gently. If you can share the first line of
Both reactions start with the same halogenoalkane and a base/nucleophile (e.g., OH⁻). The outcome depends on:
“1-bromopropane is heated with NaOH(aq) and separately with NaOH in ethanol. State the major product in each case and explain.”
