Acetone can be easily converted to isopropyl alcohol by addition of hydrogen to the carbon–oxygen double bond. calculate the enthalpy of reaction using the bond energies given. bond: c=o h–h c–h o–h c–c c–o bond energy (kj/mol): 745 432 413 467 347 358 multiple choice –61 kj +61 kj –366 kj –484 kj +366 kj

-484kJ

Explanation:

Carry out bond energy calculation

[6(C-H) + (C=O) +2(C-C)] - [(O-H) +7(C-H)+ (C-O) +2(C-C)]

Substitute the bond energy values = -484kJ

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
