<span>This is not the case in the hydrocarbon tail. The electronegativity of hydrogen and carbon are very similar, so the electron cloud is distributed evenly over the two atoms. Carbon-hydrogen bonds are said to be non-polar because they do not have positive and negative poles within themselves. Hope this helps. </span>
VII . A because it contains Br (l), Cl (g) and I (s)
Explanation:
An ionic equation will be the one in which all the participating species will be present as ions.
The given reaction will be as follows.
Balancing this equation by multiplying 
by 2 and 
by 3 on reactant side. Whereas multiply KBr by 6 on product side.
Hence, the net ionic equation will be as follows.
As both 
and 
are spectator ions. Hence, the net ionic equation will be as follows.
A would have a higher pitch
