The Iodine molecule I2 forms a temporary dipole which the electron rich double bond attacks (at the delta positive end) and this kicks out the other iodine to form I- (the electrons from the I-I bond go to the leaving group)
This has broken the double bond leaving the original carbons with one side with the I and the other with a positive carbocation. The I- then attacks the positive end of the carbocation and the Iodines are TRANS to one another. This is because I- adds from the other side to the large Iodine (to avoid steric hinderance).
It is hard to explain without the aid of diagrams I'd suggest looking up addition of bromine to double bonds, exactly the same but much more documented

What type of bond is formed between phosphorus and iodine?
covalent bond
What type of bond forms between Cesium and Iodine?
CsCl like NaCl is a salt. The cesium has an ionic bond with the chloride.
Why the brown color of bromine disappear when mixed with cyclohexene?
Halogens react with alkenes to form haloalkanes. Addition of the bromine in this case occurs across the double bond in cyclohexene. The resultant products are colourless hence the brown colour disappears.
What is formed when calcium reacts with iodine?
Calcium iodine is formed when calcium reacts with iodine. Ca(s) + I2(s) --> CaI2(s)
What is the shape and bond angles for iodine?
the shape is linear and the bond angle is 180 degree
What is double covalent bond?
A double covalent bond occurs when atoms share two pairs of electrons.
What makes a double covalent bond?
A double covalent bond occurs when atoms share two pairs of electrons.
When a dehydration reaction occurs what is produced?
a double bond
How does saturated fat effect iodine atoms?
unsaturated are oils that have double bonds in their structure because there is not enough hydrogen atoms to bond with the carbon atoms. In such case, carbon atoms bond to each others to form double or triple bonds. adding iodine, saturates the oil as iodine atoms bond to carbon atoms as if they were hydrogen atoms. This is an answer to the question that should read: How does iodine affect unsaturated fats?
What does iodine bond with?
Iodine can bont bond with itself, and other Halogens.
What is the bond length of iodine in its structure?
Bond length of iodine: 266,6 pm.
What is the addition of hydrogen across a double bond?
The reaction is known as hydrogenation.
What type of bond is formed between iodine and carbon?
Iodine and Carbon form a covalent bond. Moreover, this bond is nonpolar. Cheers, Caroline
What is an allyboration?
An allyboration is an addition reaction in which an allyl group and a boronate are added across a double bond or triple bond.
How does boron bond with iodine?
The bond is polar covalent.
What shift occurs when a saturated compound is converted into an unsaturated compound?
It gains a double bond. Unsaturated basically means it has a double bond. from C-C to C=C basically.
If the atomic number of iodine is 53 how many bond will it make with hydrogen?
One covalent bond is between iodine and hydrogen.
