Use curved arrows to predict the product in each case. KCN Acetone NaSH Br Br KCN DMSO LDA Br H3PO4 OH Heat Consider a ring contraction

Answer 1

Alkyl halide with KCN in the presence of acetone undergoes nucleophilic substitution reaction. The reaction is as follows: CJN KCN acetone Alkyl halide with KCN in the presence of N,N-dimethylacetamide undergoes nucleophilic substitution reaction The reaction is as follows: SH NaSH A Ikyl halide with KCN in the presence of DMSO undergoes nucleophilic substitution reaction. The reaction is as follows: CN KCN DMSO

Alkyl halides undergo elimination reaction in the presence of LDA to produce a misture of products. Major- HoffmannMinor-Zaitsev product Br product A lcohols react with phosphoric acid, undergo eleimination reaction to produce less substituted alkenes. The reaction is as follows
