Answer: (1) functional groups
Explanation:
Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.
Butanal is and butanone is
.
and
are functional isomers which have same molecular formula , similar masses and same number of carbon atoms per molecule but different functional groups attached.
Answer:
Explanation:
Hello,
In this case, we can analyze the colligative property of solutions - freezing point depression - for the formed solution when ethylene glycol mixes with water. Thus, since water freezes at 0 °C, we can compute the freezing point of the solution as shown below:
Whereas the van't Hoff factor for this solute is 1 as it is nonionizing and the molality is:
Thus, we obtain:
