For the following reactions :(A) CH3CH2CH2Br +KOH→CH3CH = CH2 + KBr

1.	For the following reactions :(A) CH3CH2CH2Br +KOH→CH3CH = CH2 + KBr + H2OWhich of the following statements is correct?(a) (A) is elimination, (B) and (C) are substitutionreactions.(b) (A) is substitution, (B) and (C) are addition reactions.(c) (A) and (B) are elimination reactions and (C) is addition reaction.(d) (A) is elimination, (B) is substitution and (C) is addition reaction
Answer» Correct option(d) (A) is elimination, (B) is substitution and (C) is addition reaction Explanation : CH3CH2CH2Br +KOH→CH3CH = CH2+ KBr + H2O Saturated compound is converted into unsaturatedcompound by removal of group of atoms hence, itis an elimination reaction. - Br group is replaced by - OH group hence, itis a substitution reaction. Addition of Br2 converts an unsaturated compoundinto a saturated compound hence, it is an additionreaction.

Answer»

Correct option(d) (A) is elimination, (B) is substitution and (C) is addition reaction

Explanation :

CH3CH2CH2Br +KOH→CH3CH = CH2+ KBr + H2O

Saturated compound is converted into unsaturatedcompound by removal of group of atoms hence, itis an elimination reaction.

- Br group is replaced by - OH group hence, itis a substitution reaction.

Addition of Br2 converts an unsaturated compoundinto a saturated compound hence, it is an additionreaction.
