1.

Predict the major product formed when HCl is added to isobutylene. Explain the mechanism involved.

Answer»

SOLUTION :`underset("Isobutylene")(CH_(3)-underset(CH_(3))underset("|")("C ")=CH_(2))+HCl rarr underset("(2-chloro-2-methylpropane)")(CH_(3)-overset("Cl")overset("| ")underset(CH_(3))underset("| ")("C ")-CH_(3))`
Mechanism :
STEP - 1 : FORMATION of Carbocation
`CH_(3)-underset(CH_(3))underset("|")("C ")=CH_(2)overset(H^(+))rarr underset((3^(@)"-charbocation"))(CH_(3)-overset(o+)underset(CH_(3))underset("|")("C ")-CH_(3))+underset((1^(@)"-carbocation"))(CH_(3)-underset(CH_(3))underset("|")("C ")H-overset(o+)(C )H_(2))`
Step - 2 : Attack of Nucleophile
`CH_(3)-underset(CH_(3))underset("| ")overset(o+)(C )-CH_(3)overset(Cl^(-))rarr CH_(3)-overset("Cl")overset("| ")underset(CH_(3))underset("| ")("C ")-CH_(3)`
