Question

2. (CH 6) Rank the five halogen elements in terms of increasing electronegativity. 3. (CH 6) Draw a possible Lewis structure for the two compounds CH4 and CH3C. Identify which one would be polar and w

Answer 1

Answer:- 2) Electronegativity describes the tendency of an atom to attract the shared pair of electrons or electron density towards itself.

Electronegativity in halogens:- there are 5 halogens as asked in the question = Fluorine (F), Chlorine (Cl) , Bromine (Br) , Iodine (I) , Astatine (As)

And the increasing order of electronegativity in these halogens is as :-

As < I < Br < Cl < F.

Where, Fluorine is having the highest electronegativity.
