Why are lots of products produced in radical substitution

A

As more than one substitution happens so more termination steps occur

16
Q

Heterolytic

A

The bond beaks unevenly with one of the bonded atoms receiving both electrons from the bonded pair

17
Q

Why is e/z isomerism shown

A

Due to carbon double bond which restricts rotation. Each carbon of the double bond is attached to two different groups

18
Q

Stereoisomerism

A

Same structural and molecule formula but different arrangement of atoms in space

19
Q

how are pi bonds formed

A

pi bonds are formed by the sideways overlap of 2 p orbitals in each carbon atom.Its formed above and below the atom

20
Q

j

A

j

21
Q

difference between pi and sigma bond

A

pi bond has a lower bond enthalpy .sigma bonds form between atoms and pi bonds form above and below atoms

22
Q

why does cracking form lots of products

A

as any cc bond in alkane can break

23
Q

why does this(a compound with 2 double bonds) not have cis/trans isomerism

A

as the c in the c=c bond are joined to two groups that are the same

24
Q

temp and conditions needed to make a polymer

A

ziegler catalyst with high temperature
