Acompound has the formula c3h6o. there are no carbon-carbon double bonds in the molecule give the possible structural formulae and names for the compound

Explanation:

Calculating the double bond equivalence as:

DBE =  C - (H/2) - (X/2) + (N/2) +1

Where

C is the number of carbon atoms

N is the number of nitrogen atoms

X is the number of halogens

H is the number of hydrogen atoms

So, according to the formula, C₃H₆O,

DBE =  3 - (6/2) - (0/2) + (0/2) +1 = 1

It means there is one double bond and it is given in the question that it is not between the carbon.

It can be between oxygen and carbon or a ring.

The possible structures are shown in the image.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
