C28h36o18 would be classified as what? how do you know this? m

It is an saturated compound since there are no c-c double or tripple bonds.

Explanation:

If we had such double or tripple bonds the remaining o &H atoms cannot be accommodated to the carbon chain.

the carbon skeleton has (26×2)+6=58 valence electrons

O occupies 2 for each

18×2= 36

,58-36=22

only 22H can be directly bonded to the carbon skeleton.

remaining H= 14

therefore 7carbonyl carbon atoms will have to turn into carbinol carbon atoms .

so no space for c-c double bonds

i think its 5049.

i hope this !
