Question

The number of moles of ethanol chloride will produce 10.2 g of ethanoic anhydride on reaction with sodium acetate
A. 0.51 mol
B. 1.02 mol
C. 0.10 mol
D. 10.2 mol

Answer 1

Correct Answer - C
`underset(1 mol)(CH_(3)COCl) + NaOCOCH_(3) rarr underset(102 g)((CH_(3)CO)_(2) O + NaCl)`
10.2 g of ethanoic anhydride will be obtained from acetyl chloride `= (1)/(102) xx 10.2 = 0.10 mol`
