Question

In a reaction

CH_{2} & - & OH \\ | & & \\ CH_{2} & - & OH \end{matrix}$$ Where M = molecule; R = reagent M and R are.

• A. $CH_{3}CH_{2}Cl$ and NaOH
• B. $CH_{2}Cl - CH_{2}OH$ and $\text{aq. }NaHCO_{3}$
• C. $CH_{3}CH_{2}OH$ and HCl
• D. $CH_{2} = CH_{2}$ and heat

Answer 1

Answer: (B)

$CH_{2}Cl - CH_{2}OH$ and $\text{aq. }NaHCO_{3}$

Answer 2

$CH_{2} = CH_{2}\overset{\quad HOCl\quad}{\rightarrow}\underset{\underset{Cl}{|}}{CH_{2}} - \underset{\underset{OH}{|}}{CH_{2}}\overset{\quad aqNaHCO_{3}\quad}{\rightarrow}$

$\underset{\text{Glycol}}{\underset{\underset{CH_{2} - OH}{|}}{CH_{2} - OH}}$
