Explanation / Answer

1) n-butyl alcohol is limiting reactant.

2) Theorotical yield-

1 mole of n butyl alcohol = 1 mole of n butyl acetate

74.12 = 116.2

Therefore 22.3 gm of butyl alcohole = 22.3 x 116.2 / 74.4

= 14.25 gm

3)22.3 butyl alcohol gives 14.25 gm of butyl acetate

100 gm of butyl alcohol gives = 22.3 x 14.25/100

=3.14 %
