Find out distance between two iodine atoms (in Å) in trans-Ethene. (given ® Bond length of C = C is 1.33 Å, Bond length of C-I bond is 2.10 Å) -

To find the distance between two iodine atoms in trans-Ethene, we need to consider the molecule as a whole. Trans-Ethene (C2H2I2) is a linear molecule with the iodine atoms on opposite sides of the carbon-carbon double bond.

Step 1: Identify the relevant bond lengths. We are given that the bond length of C=C is 1.33 Å and the bond length of C-I is 2.10 Å.

Step 2: Calculate the total distance across the molecule. The distance between the two iodine atoms will be the sum of the C=C bond length and two times the C-I bond length (since there are two C-I bonds in the molecule).

So, the calculation will be:

Distance = 1.33 Å (C=C bond) + 2 * 2.10 Å (C-I bond) Distance = 1.33 Å + 4.20 Å Distance = 5.53 Å

So, the distance between the two iodine atoms in trans-Ethene is 5.53 Å.
