Ethanoic acid is warmed with thionyl chloride. The products are

A $(CH X_{3} CO) X_{2} O$ , $SO X_{2}$ and $H X_{2} O$
B $CH X_{3} COCl$ , $H X_{2} SO X_{4}$ and $HCl$
C $CH X_{3} COCl$ , $SO X_{2}$ and $HCl$
D $CH X_{3} CHO$ , $SO X_{2}$ and $HCl$

Answer: C

CH X_{3} COOH + SOCl X_{2} CH X_{3} COCl + SO X_{2} ↑ + HCl ↑

. The by-products are gases, which is why

SOCl X_{2}

is a convenient reagent for acid chlorides.
