A compound with molecular formula C_4H_{10}O_3 is converted by the action of acetyl chloride to a compound of molecular mass 190. The original compound (C_4H_{10}O_3) has how many OH groups?
Step-by-Step
\begin{matrix} R & -& OH & + & CH _3 COCl & \rightarrow & R &-& OCOCH _3&+& HCl \\ &&&& \text {M} &&&& \text {(M + 42) }\end{matrix}
A cylation of each OH group results in an increase of molecular mass of 42. In the given problem molecular mass of the compound increases by 84 on acylation. Therefore, the compound has two OH groups
