In Zeisel's method for the detrmination of methoxyl groups, a sample of `2.68` gm of a compound (A) gave `14.08` gm of AgI. If the molecular weight of compound (A) is 134, the number of `(--OH_(3))` group(s) in the compound (A) is:

A

1

B

2

C

3

D

4

Text Solution

Verified by Experts

The correct Answer is:
C
`2.68` gm of (A) gives `14.08` gm og AgI
134 gm of (A) gives `(14.08xx134)/(2.68)-704` gm of AgI
`=(704)/(235)`mol of AgI
`=3 (OMe)` groups.
