Question

The reagent X in the reactions $(C{H}_3{)}_{3}CCH=C{H}_2\underset{THF}{\stackrel{X}{}}Y\underset{NaOH}{\stackrel{NaB{H}_4}{\to }}(C{H}_3{)}_3-\underset{OH}{\underset{|}{C}}-CH-C{H}_3$

• A. $H_3{O}^{+}$
• B. $Hg(C{H}_{3}COO{)}_2$
• C. $O{H}^{-}$
• D. $HCOOH$

Answer 1

The correct option is B $Hg(C{H}_{3}COO{)}_2$

b)
Oxy mercuration-demercuration: with mercuricacetate (in THF) followed by reduction with $\frac{NaB{H}^4}{NaOH}$ is an example of hydration of alkene according to markowni koff's rule.
$(C{H}_3{)}_{3}C-CH=C{H}_2\underset{THF}{\stackrel{(C{H}_{2}COO{)}_2{H}_2}{\to }}(C{H}_2{)}_{2}C-\underset{OOCC{H}_3}{\underset{|}{CH}}-C{H}_2-HgOOCC{H}_3$
