Acetone is heated with ethylene glycol, HOCHX2CHX2OH, in the presence of dry HCl. The main product is
A2,2-dimethoxypropane
Bpropan-2-ol
C2,2-dimethyl-1,3-dioxolane
D2-methyl-1,3-dioxane
Answer: C
A carbonyl compound and a 1,2-diol with an acid catalyst give a cyclic acetal (ketal). Acetone and ethylene glycol give the five-membered ring 2,2-dimethyl-1,3-dioxolane with loss of HX2O.
