Compounds (A) and (C ) in the following reactions are
`CH_(3)CHO overset((i)CH_(3)MgBr)underset((ii)H_(2)O)to(A) overset(H_(2)SO_(4),Delta)to(B)overset("Hydroboration oxidation")to (C)`

Options

A. identical
B. positional isomers
C. functional isomers
D. optical isomers

Answer

B

Explanation

` underset(" Ethanal") (CH_3CHO) underset( (ii) H_2O) overset((i) CH_3Mg)to CH_3- underset(CH_3) underset(|) (CH) - OH underset(" Dehydration") overset(H_2SO_4Delta )to `
` underset(B) underset(" Propene") (CH_3-CH= CH_2 ) underset( ("Hydroboration Oxidation ") ) overset((i) BH_3(ii) H_2O_2//OH^(+)) to CH_3- underset("Propan"-1-ol) (CH_2)- CH_2OH`
