Answer:

Halogenation.

Explanation:

Hello,

In this case, we must remember that group VIIA elements are known as halogens which include F, Cl, Br, I and At. Now, when an alkane reacts with the diatomic form of one of those halogen a haloganation chemical reaction occurs forming an alkyl halide and a hydrogen halide. For instance, for ethane, if it reacts with iodine, ethyl iodide and hydrogen iodide are yielded based on the given example:

CH_3-CH_3+I_2\rightarrow CH_3-CH_2-I+HI

Best regards

Alkanes are saturated hydrocarbon, that is they contain hydrogen and carbon without a double or triple bond between the carbon atoms, e.g. ethane, propane. Group 7a in the periodic table are called halogens e.g chlorine, bromine. Alkanes react with halogens in a reaction called substitution, where halogens replace hydrogen atoms in alkanes.

Explain the following phenomena. why Fluorine has lower electron affinity than chlorine​
Radda [10]

Electron affinity for fluorine is than chlorine most likely , due to the electron repulsion that occur between the electron where n= 2 . the elements in the second period have such small electron clouds that electron repulsion is greater than that of the rest of the family.

8. Based on the formula, predict whether each of the following compounds is primarily ionic or primarily covalent. a. sodium iod
Lina20 [59]

primarily ionic  include = sodium iodide( NaI) ,   calcium chloride  ( CaCl2)


primarily covalent    include  - Ammonia (NH3) , Methane ( CH4)  and  

                                                   Glucose  (C6H12O6)


Explanation

ionic  bond  is formed  when  there is complete transfer of electron between atoms. It occur  between metal  which  donate electrons and  a  non  metal which accept  electrons.

 for  example  in  formation  of CaCl2,   ca  donate  2 electron to 2  Cl atom, while  2 Cl atom accept the 2  electrons  to form ionic bond.

 Covalent bond  is formed  when two or  more  non  metal  form bond by sharing  electrons pairs.

For  example in NH3   3 pairs of electron are shared.  to form covalent bond.
