7) option D is correct
Explanation: Reaction of alcohol with TsCl, pyridine produces tosylate as product. Reaction of tosylate with NaOH produces more substituted alkene as product. Hydroboration-oxidation of alkene with BH3, THF and H2O2, NaOH, H2O produces least substituted alcohol as product.
8) option D is correct
Explanation: NaNH2 is a strong base which gives dehydrohalogenation and produces acetylide ion as product.
