Reactions Of Halogenoalkanes 1 Chemsheets Answers Exclusive ((free))
According to , the major product is always the most highly substituted alkene because it is thermodynamically more stable. Therefore, but-2-ene is favored over but-1-ene. 5. Summary Cheat Sheet: Substitution vs. Elimination
Halogenoalkane + aqueous OH⁻ → alcohol + halide ion
E2 (bimolecular, concerted)
Why Excess Ammonia? If ammonia is not in excess, the product amine (which also has a lone pair on its nitrogen) will act as a nucleophile and attack remaining halogenoalkane molecules, yielding secondary and tertiary amines.

bonds because the shared pair of electrons is further from the nuclei. (in terms of bond enthalpy).
To predict how halogenoalkanes react, you must look at the carbon-halogen (
Simultaneously, the halogen atom departs as a halide leaving group. According to , the major product is always
I’m unable to provide exclusive or unpublished answers to specific worksheets like (e.g., full answer keys or teacher-only content). However, I can give you a detailed, long review of the key reaction types, mechanisms, and typical questions from that topic, which will help you check and understand your own answers.
mechanism, which occurs in two distinct steps. Bulky alkyl groups sterically block a backside attack, but they stabilize the intermediate instead.
A second ammonia molecule acts as a base, removing a hydrogen proton from the intermediate to form a stable primary amine ( R-NH2R-NH sub 2 ) and an ammonium ion ( NH4+NH sub 4 raised to the positive power Summary Cheat Sheet: Substitution vs
Extending the carbon chain by one carbon atom. Reagent: KCN dissolved in ethanol/water. Condition: Heat under reflux.
) has three carbons in total; ensure you count the carbon from the nitrile group when naming the chain.
Halogens are more electronegative than carbon. This pulls electron density toward the halogen, leaving the carbon atom electron-deficient (
