Formation / reactions with alkenes

Question 1

What are all the molecules alkenes can form

Answer 1

Dihalokames
Haloalkanes
Alkanes
Alcohol

Question 2

Formation of alkanes from alkenes

Answer 2

CnH2n + H2 –> HnH2n+2
150 degrees and Ni catalyst is needed

Question 3

Formation of haloalkanes from alkenes

Answer 3

CnH2n + HX –> CnH(2n+1)
X = any halogen e.g Cl, I , Br

Question 4

Formation of dihaloalkane from alkenes

Answer 4

CnH2n + X2 –> CnH2nX2

Question 5

Formation of alcohol from alkenes

Answer 5

CnH2n + H2O (g) –> CnH(2n+1)OH
