Question 4

Multistep Synthesis

Answer 4

A more than one step reaction

Question 5

Simultaneous reaction

Answer 5

When substances react independently and at the same time

Question 6

Consecutive reactions

Answer 6

Reactions carried out in a sequence

Question 7

Intermediate

Answer 7

Substance produced in one step and consumed in another during a multistep synthesis
