One structural isomer of $$\mathrm{C_2H_4I_2}$$ contains both iodine atoms attached to the same carbon atom. The bond length of C-I is $$2.10 $$. Assuming tetrahedral angles, the distance between the two iodine atoms is (given that $$sin 54.75° $$ = $$ 0.815$$ and $$ sin 109.5° = 0.94$$)

A

$$2.10 A$$

B

$$2.47 A$$

C

$$4.20 A$$

D

$$3.42 A$$
