Question

how to convert ISO butyl chloride to tertiary butyl chloride?

Answer 1

tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at ..... kinetics) and the equilibrium itself not favoring product enough for complete conversion. 

 So if we used Cl instead of OH, we'd have n-butyl chloride, s-butyl chloride, t-butyl chloride, and isobutyl chloride .
