JEE Main 2020 Chemistry question

Two compounds A and B with same molecular formula () undergo Grignard's reaction with methylmagnesium bromide to give products C and D. products C and D show following chemical tests.

| Test | C | D | |---|---|---| | Ceric ammonium nitrate Test | Positive | Positive | | Lucas Test | Turbidity obtained after five minutes | Turbidity obtained immediately | | Iodoform Test | Positive | Negative |

C and D respectively are :

• (A) ; \mathrm{D=H_3C{-}CH_2{-}CH(OH){-}CH_3}
• (B)\mathrm{C=H_3C{-}CH_2{-}CH_2{-}CH_2{-}OH} ;
• (C)\mathrm{C=H_3C{-}CH_2{-}CH(OH){-}CH_3} ; Correct
• (D)\mathrm{C=H_3C{-}CH_2{-}CH_2{-}CH_2{-}OH} ; \mathrm{D=H_3C{-}CH_2{-}CH(OH){-}CH_3}
