Answer 1

In reaction sequence

CH₂OH

CH₂ = CH₂ □(→┴Hypochlorous) M □(→┴R )|

CH₂OH

molecule 'M' and reagent 'R' respectively are

(a) CH₃CH₂Cl and NaOH

(b) CH₃CH₂OH and H₂SO₄

(c) CH₂Cl . CH₂OH and aqueous NaHCO₃✔✔✔

(d) CH₂ — CH₂ and heat

Answer 2

In the reaction sequence,we have to determine the molecule'M' and reagent 'R'

and the answer is option (c) CH₂Cl . CH₂OH and aqueous NaHCO₃

•a molecule of hypochlorous acid (HOCl) when added to C=C / carbon-carbon double bond of ethylene ,it formed CH2Cl—CH2OH (molecule M) and then the hydrolysis process is happened with aqueous sodium bicarbonate NaHCO3 (reagent R) and forms ethylene glycol (CH2OH—CH2OH)

the reaction would be

CH2=CH2 —HOCl—› CH2OH-CH2OH —aq sodium bicarbonate—› CH2OH-CH2OH
