For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length. (A) C-I (B) H-I (A, B) fill in the blank 1 (C) H-Cl (D) H-I (C, D) fill in the blank 2

i)  B

ii) D

Explanation:

Bond length is determined by the size of the atoms involved and the bond order

A) C-I

B)  H-I

answer : H-I has the shortest bond length because H has an electronegativity value of 2.2  while C has an electronegativity value of 2.5 hence the bond between H-I is greater than C - I due the electronegativity difference between H-I is greater as well.

C) H-Cl

D) H-I

answer :  H-Cl has the shortest bond length due the electronegativity difference between H-CI is greater as well.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
