reaction mechanisms.

Question 1

Halogenoalkane - neucleophillic substitution (hydrolysis)

Answer 1

Question 2

alkenes - electrophillic addition.

Answer 2

Question 3

Alkane + Hyfrogen halide.

Answer 3

Question 4

Alkane - radical substitution.

Answer 4

Br₂—>2Br* UV (homolytic fision)

Br* +CH₄—>CH₃*+HBr

CH₃*+Br₂—> CH₃Br +Br*

then termination.
