The best way of characterizing the sucralose would be to say it is a molecule, but there is no such option. So, the closest options is "Compound", because it is composed by more than one element.
So, first blank is "Compound".
The elements on it are H, C and O. From an electronegativity table, we can see that the electronegativities are approximately:
H: 2.1
C: 2.5
O: 3.5
So, the least electronegative is H.
Second blank is "hydrogen".
The normal rule to follow is the octet rule, so we complete the shell by getting 8 electron in it.
But, the hydrogen has only 1 electron and it is on the first shell, so it can't complete the octet rule like normal, it follows the duet rule, that is, it completes 2 electrons.
Third blank is "Du".
The Sucralose is composed by nonmetals and hydrogen only, so they don't bond by ionic bonds, they form covalent bonds. Thus, they don't dissociate into ions.
Fourth blank is "False".
A bond is considered polar if the electronegativity of their elements are dfferent enough. When bonding C-C, both have the same electronegativity, so they are not polar, that is, they are non polar covalent bonds.
Fifth blank is "Non polar covalent".
O-H, on the other hand, have a very different electronegativities, one is 2.1 and the other is 3.5, so the bond will be polar.
Sixth blank is "Polar covalent".
Between the solid, liquid and gas phases, the gas is when the molecules are the most apart and solid is when the molecules are the closest. Since it is solid, the particules will be closer.
Seventh blank is "Closer".
