In any distillation for maximum efficiency of the column, the distilling flask should be approximately 1/2 full of liquid. Comment on this fact in terms of a) a flask that is too full and b) a flask that is nearly empty.
I don't know about a)...
For b), it shouldn't be nearly empty because the liquid might dry out before you can get the distilled solution? Or it won't make enough distilled solution???

a. When boiling and bubbling, the liquid could easily splash over into the Liebig condenser.
b. If the distillation flask boils dry, it will crack and shatter. And you won't get much distillate, of course! But the question does talk about efficiency, and that, to my mind, includes possible destruction!

to begin with there r different types of distillation.in dry distillation,the container will be least filled.(gravimetry).
allowing a little space above boililng substance allow the hot vapours to rise up easily ,which can travel through a tube,where coolin can occur.
a flask can be nearly empty provided the material of the flask is heat resistent.(silica crusible).this type of experiment is carried out in gravimetry.
