The number of alkoxy groups in an organic compound, `A(OR)_(x),` may be determined by the sequential reactions:
`A(OR)_(x)+xHIrarrA(OH)_(x)+xRI`
`RI+Ag^(+)+H_(2)OrarrROH+AgI(s)+H^(+)` When 4.8 gm of the organic compound, `A(OR)_(x),` (molar mass=240 gm//mol) is treated as above, 9.4 gm Agl is precipitated. The number of alkoxy groups in the compound is:
