Question

complete full mechanism with arrows, dot structure and narration (iniation, propagation and termination)

of the following:

chlorination of methylene to produce chloroform.

be sure to show the radical.

use the line structure to show the bonds

Answer 1

CHLORINATION OF METHYLENE TO PRODUCE CHLORO FORM. I - INITIATION It proceeds by free radical chain mechanism, in the industrial synthesis of chlonform Concz] It involves the following steps, It involves homolytic cleavage of chlorine molecule initiated by UV radiation ox sunlight. circ → Co + c. T - PROPAGATION ( two steps). STEP-1 [ + cl. → C-H + H-C1 c! STEP 2 C-H + Cl - cl → This radical will chain reaction if chlorine. S C-H + ci propagate continously causing a there is a presence of sufficient C-H + Cl-Cl → + CH C-H اع C + H + c-cl → chclz + cl. chloroform molecules with longer results in Tui Termination carbon chain.
