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
covalent bond
CsCl like NaCl is a salt. The cesium has an ionic bond with the chloride.
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.
Calcium iodine is formed when calcium reacts with iodine. Ca(s) + I2(s) --> CaI2(s)
the shape is linear and the bond angle is 180 degree
A double covalent bond occurs when atoms share two pairs of electrons.

a double bond
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?
Iodine can bont bond with itself, and other Halogens.
Bond length of iodine: 266,6 pm.
The reaction is known as hydrogenation.
Iodine and Carbon form a covalent bond. Moreover, this bond is nonpolar. Cheers, Caroline
An allyboration is an addition reaction in which an allyl group and a boronate are added across a double bond or triple bond.
The bond is polar covalent.
It gains a double bond. Unsaturated basically means it has a double bond. from C-C to C=C basically.
One covalent bond is between iodine and hydrogen.
