Question

Show the following (Label reagents, products, reactants, and mechanisms): Reaction of Alkyl halide (geminal) to synthesize alkene oralkyne (note mole equivalence of Nu:) Reaction of Alkyl halide (vicinal) to synthesize alkene or alkyne (note mole equivalence of Nu:)

Answer 1

Bow # In a Alkyl dihatides, It both the halide groups are present on Same Conbon atom then those are called geminal alkyl hatides. 80 R-6-d-R' on H - It bok the two halides are present on adjacent Cerbons then thuse Alkyl dihalides are called as Vicinal Alkyl dihalides Bor Br Rc-c-Rl # # nomally shong base like Nalle should use to generate alkynes. acidie Det hydro sen City Mallik_l Badh, feu R-CECH I ex elimination R a Es Elimination Nann Alkenry V halide on # It R-cace In Mechanism electrons flow showed in red into am a Equivalent) of Base is required to get Alkynes B) In this case also strong base Callk) required to generate Alkynes Berit Nount H Nalth E2-eliminchen RUM la climination R-CECH Nakh R-CECO - this is good procedure to make Alkynes
