Which of the following compounds shall not produce propene by reaction

1.	Which of the following compounds shall not produce propene by reaction with HBr followed by elimination reaction ?
Answer» `H_3C-overset(H_2)C-CH_2OH` `H_2C=C=O` `H_3C-overset(H_2)C-CH_2Br` Solution :(a)The strained three-membered ring opens upon treatment with HBR to give n-propyl bromide which upon elimination of HBr gives propene (b)`UNDERSET"n-Propyl alcohol"(CH_3-CH_2-CH_2OH)underset(-H_2O)overset"HBr"to underset"n-Propyl bromide"(CH_3CH_2CH_2Br) underset"(-HBr)"overset"Elimination"to underset"Propene"(CH_3-CH=CH_2` (d)`CH_3CH_2CH_2Br` gives `CH_3CH=CH_2`. Thus, `H_2C=C=O` does not give `CH_3CH=CH_2` . i.e., OPTION (c ) is CORRECT.
