Answer #1

1. NaNH2 CH3 2. EtBr (1 equiv.) Pd(PPh3)4, Cul, Et3N CCH Na/NH3 H3C CH3

Explanation: NaNH2 is a strong base which abstracts acidic proton and forms acetylide anion. Now alkylation of acetylide anion with etBr produces an extended carbon chain. Now, deprotonation of alkyne with et3N and reaction with palladium compound produces an extended carbon chain. Reduction of alkyne with Na inliq.NH3 produces trans-alkene as product.
