* Hướng dẫn giải

Đáp án C

CH₃CH₂OH $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$ CH₂ = CH₂ + H₂O

CH₃-CH(OH)-CH₃ $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$ CH₃-CH=CH₂ + H₂O

CH₃-CH₂-CH₂OH  $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$CH₃-CH=CH₂ + H₂O

(CH₃)₂CH-CH₂OH $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$ (CH₃)₂C=CH₂ + H₂O

(CH₃)C-OH $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$(CH₃)₂C=CH₂ + H₂O

(CH₃)₂CH-CH(OH)-CH₃ $\stackrel{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{n}\right), \mathrm{t}°}{\rightleftarrows }$
